FAQ men's long-sleeved T-shirts

Why choose a long-sleeved T-shirt over a light sweater?

Long-sleeved T-shirts are thinner, lighter, and more versatile than sweaters. Their reduced thickness means they can be worn on their own in mid-season or as a base layer under other garments in colder weather. Even lightweight sweaters add bulk and limit layering options.
Long-sleeved cotton T-shirts also dry faster, are easier to wash and crease less. In terms of comfort, cotton jersey is breathable throughout the day, whereas some knits can be warmer than necessary. For men looking for a classic, versatile and functional basic, this is often the best compromise between warmth and lightness.

How to choose the right fit for a men's long-sleeved T-shirt?

The cut depends on your body type and intended use. The regular fit suits most body types: it hugs the body without being tight and offers comfortable ease for everyday wear. For slim men who want to structure their silhouette, a slightly fitted version shapes the chest without compressing it. The loose fit is for those who prefer a more relaxed look, but requires careful coordination to remain elegant. The choice of size also depends on your personal comfort. Visit the brand's size guide page. Sizes vary from one brand to another, which is why it is important to check size correspondences. A T-shirt that is too tight will highlight flaws, while one that is too loose will look sloppy. The right fit falls naturally on the shoulders and leaves two fingers' width of space at the chest.

Long-sleeved T-shirt with a round neck or V-neck: which one to choose?

The crew neck is the default versatile choice. It works with all body types and can be worn on its own or layered under a jacket, overshirt, or one of the sweatshirts in your wardrobe. It is the easiest neckline to incorporate into an everyday look. The V-neck opens up the chest and visually lengthens the neck. It is well suited to men with round faces or short necks, as it creates a vertical line that slims the silhouette. Men will appreciate this option for adding variety to their wardrobe. However, the V-neck works best as a visible piece (not as an underlayer). For a complete wardrobe, it's ideal to have both: the crew neck for most situations, and the V-neck for slightly more formal occasions or under a blazer.

What is the ideal weight for a high-quality long-sleeved T-shirt?

The weight measures the fabric's weight in grams per square meter. Below 140 g/m², the fabric appears very thin, almost transparent, and quickly loses its shape. Between 150 and 170 g/m², you get a lightweight T-shirt that is suitable for summer or as a base layer. The ideal range for everyday use is between 180 and 220 g/m²: the fabric has density, retains its shape after numerous washes, and drapes beautifully. Above 220 g/m², the fabric is closer to a thick sweatshirt-type jersey. For a durable and comfortable men's long-sleeved T-shirt for everyday wear, a minimum of 180 g/m² is a good benchmark for quality, regardless of the color chosen.

What materials should you choose for a comfortable long-sleeved T-shirt?

Cotton remains the benchmark for everyday comfort. It absorbs moisture, breathes well, and offers a naturally soft feel. The material is essential for every man's well-being.
100% cotton jersey is the most common and popular fabric for men's long-sleeved T-shirts. A cotton-elastane blend adds flexibility for greater freedom of movement without deformation.
Organic cotton T-shirts offer the same properties with a more environmentally friendly cultivation process.
Avoid 100% synthetic fibers if you wear your garment next to your skin: they retain odors and are less breathable. Cotton-polyester blends offer resistance but at the expense of feel. The colors available vary depending on the collection. For optimal comfort, 100% cotton or cotton with a small percentage of elastane remain safe bets.

How can you pair a long-sleeved T-shirt with jeans or chinos?

When wearing jeans, keep it simple: a black, white, or navy blue T-shirt with raw denim jeans makes for a solid base.
Chinos go perfectly with earthy colors like beige or gray. Neutral colors are the easiest to match.
A white T-shirt with beige chinos creates an effective casual-chic look. For a dressy bottom, stick to subtle shades and a well-fitting round neckline. Add a blazer or structured jacket to elevate the silhouette. The rule to remember: the dressier the bottom, the more impeccable the T-shirt should be in terms of cut and fabric.

Is a men's long-sleeved T-shirt suitable for the office or for casual chic?

For a relaxed office environment, a long-sleeved T-shirt with a round neckline in a subtle shade (navy blue, gray) paired with chinos works perfectly. Worn under a blazer, it replaces a shirt for a casual yet polished look.
Professional dress codes have evolved considerably, and a well-cut long-sleeved T-shirt is now accepted in many contexts. It is the ideal base layer for jeans. Paired with dark jeans and leather shoes, it creates a look that is effortlessly put together. The key lies in the quality of the fabric and the cut: a well-fitting, densely woven cotton men's T-shirt with clean finishes rivals many casual shirts in terms of elegance.

Men's long-sleeved T-shirts

Long-sleeved T-shirts are an integral part of any man's wardrobe and can be worn in a wide variety of situations. Collars become misshapen after a few washes. Cotton becomes rough. Colors fade. Men's long-sleeved T-shirts should be a reliable staple, yet few T-shirts truly stand the test of time.

The problem isn't the garment itself. It's what goes into it. Poorly selected cotton, insufficient weight, sloppy finishing: that's what turns a T-shirt into a disappointment at the bottom of the drawer.

At SERGE BLANCO, men's long-sleeved T-shirts are made from a different quality of fabric. They are made from cotton jersey with a weight ranging from 160 to 210 g/m² depending on the model, with ribbed collars that retain their shape and colors that are designed to withstand repeated washing. All this in a range of sizes from S to 6XL, with sizes to suit all builds. The choice of sizes is essential, because a quality T-shirt must suit all body types. Please consult the size guide before making a purchase. Black, white, khaki, navy blue: these colors are designed to fit into a man's wardrobe. This timeless style suits any modern man. Comfort and style are not options, they are manufacturing requirements. A design conceived in France, with details that stand up to use.



Materials and finishes: what makes the difference in a men's long-sleeved T-shirt


Cotton jersey, weight, and stretch: choosing the right fabric

Not all cotton T-shirts are created equal. The material used to make a long-sleeved T-shirt determines its comfort, durability, and longevity. Two criteria can be used to quickly sort through the options: the manufacturing process and the weight.

Jersey offers a smooth surface, a regular drape, and immediate softness. It is the most common knit fabric used for men's T-shirts, and for good reason: it adapts to all uses. Slub jersey, on the other hand, has slight irregularities in the yarn. These variations in texture give the T-shirt a more raw, lively look. Visually, the finish appears less uniform than a perfectly smooth surface, which adds character without the need for a print.

Weight is measured in grams per square meter. A long-sleeved T-shirt weighing 140-160 g/m² will be light and fluid, ideal as a base layer or for warm seasons. A T-shirt weighing 180-220 g/m² offers more structure and density, perfect for cooler seasons. It retains its shape better with repeated washing and hangs more neatly on the body. For a men's long-sleeved T-shirt that you plan to wear regularly, ideally aim for a weight of more than 160 g/m².

The addition of elastane (usually 5 to 7%) gives cotton a stretch effect, i.e. elasticity. The T-shirt moves with you without losing its shape. 100% cotton garments offer a more natural feel and maximum breathability. Cotton-elastane blends focus on support, flexibility, and stretch. Both options are equally good: it all depends on whether you prioritize stretch for comfort or the raw material.

When purchasing, lightly crumple the fabric in your hand and then release. High-quality cotton quickly regains its shape. Lower-quality cotton retains the crease.


Ribbed cuffs, double stitching, and dyes: the details that matter

The finishes on a men's long-sleeved T-shirt reveal the quality of its manufacture. Ribbed cuffs, for example, keep the sleeves in place without compressing the forearm. They also prevent the fabric from riding up during the day. Double stitching at the waist and hems reinforces areas of tension.

The collar is the area most prone to deformation. A ribbed crew neck with an elastic band is much more resistant than a simple hemmed neckline. After several washes, the difference becomes apparent: the former retains its shape while the latter begins to stretch out.

When it comes to colors, the dyeing method often plays an overlooked role. Reactive dyes penetrate deep into the fiber. Pigment dyes settle on the surface. They offer an interesting vintage effect but fade more quickly when washed. For a plain T-shirt that you want to keep its color over time, reactive dye is preferable.

For care, it is recommended to wash T-shirts at 30°C after turning them inside out. Avoid using a dryer. Ironing at a low temperature is sufficient if necessary. These simple steps will prolong the life of the T-shirt and preserve its colors over time.



Collars, sizes, and colors: choosing the right men's long-sleeved T-shirt


Round neck or V-neck, regular fit or oversized: find the one that's right for you

The crew neck remains the classic choice for men's long-sleeved T-shirts. Versatile, it works on its own with jeans or under a jacket. It suits all body types and requires no special thought to wear with style. It is the default neckline for a men's wardrobe built on simplicity.

The V-neck adds a more formal touch. It opens up the chest, visually lengthens the silhouette, and pairs particularly well with a blazer or overshirt. For men with thick necks or round faces, this neckline can create a more refined look. Be careful, though: a V-neck that is too deep can quickly become too casual.

When it comes to silhouettes, the regular fit remains a safe bet. It hugs the body without being tight, offers natural freedom of movement, and suits most body types. The oversized version is part of a more assertive streetwear trend. It works well on slim figures looking for volume, but requires careful pairing to avoid looking "too big." For larger builds, a regular T-shirt with a good shoulder fit will be more flattering.

The online size guide makes choosing easy. SERGE BLANCO offers sizes from S to 6XL. This range of sizes allows every man to find the right T-shirt for his build, without compromising on style. Large sizes have their place among our products.


From black to khaki: which colors to choose

Three colors form the basis of a men's long-sleeved T-shirt wardrobe: black, white, and navy blue. These basic, understated T-shirts go with everything, can be paired with any bottoms, and will last for years. Owning two or three T-shirts in these shades ensures you'll always find one to match your outfit of the day. The durability of the colors is also an important factor. Understated colors remain the most versatile. Dark colors are also very popular.

Khaki is an interesting alternative. Neither too bright nor too neutral, it works just as well with raw denim as it does with beige chinos. Bronze, green, and gray complete the palette for those who want to mix things up without going overboard.

SERGE BLANCO renews its colors each season while retaining its classic styles. Plain T-shirts form the basis of the collection, with printed designs and graphic details adding interest to the silhouettes. The brand also offers capsule collections in partnership with sports clubs (Stade Toulousain, Toulouse Football Club, Rugby Club Toulonnais, and Rugby Club Vannetais). These limited editions are collector's items for sports fans.



How to wear a men's long-sleeved T-shirt?


With jeans, chinos, or dress pants: the right choices

A black long-sleeved T-shirt with raw denim is the perfect compromise. Look no further for a neat and effective everyday look. To soften the outfit, opt for white sneakers or leather boots depending on the style you're going for.

A white T-shirt paired with beige chinos creates an instantly chic, casual look. The light-on-light contrast works as long as the cuts are clean. Baggy chinos or a loose-fitting top will make the outfit lose its structure.

For occasions that call for a more polished or formal look, wear a long-sleeved T-shirt under a blazer with dress pants. Choose a round-neck T-shirt in a subtle color (navy blue or gray) with sufficient weight so that the fabric does not crease under the jacket. The look is more casual than a shirt, but still perfectly suited to today's professional environments.

Dark denim remains the best match for a men's long-sleeved T-shirt. Straight or slim cuts create a balanced look. Fine knit sweaters or sweatshirts worn over the top complete the look without overloading it.


As an overlay or as the main piece?

The men's long-sleeved T-shirt is not just a mid-season garment. It is a key piece that can be worn all year round depending on how you style it.

On sunny days, wear it on its own with the sleeves rolled up to the forearms. A lightweight jersey T-shirt (150-160 g/m²) in a light shade is perfect for mild days. Light colors create their own unique vibe. The look remains casual and smart.

In winter, it becomes the first layer. Under a sweater or overshirt, the long-sleeved T-shirt provides warmth and comfort without unnecessary bulk. Sweaters are best worn over a thin cotton T-shirt: softer on the skin, easier to wash, and more versatile than a knit worn directly on the body.

In mid-season, slip it under a light jacket, blouson, or parka. The long-sleeved T-shirt provides a thin mid-layer that regulates temperature without adding bulk under your clothes. For a polished look, subtle colors are the easiest to layer.



At SERGE BLANCO, men's long-sleeved T-shirts are part of this thoughtful wardrobe approach. Pieces designed to be worn alone or layered, in fabrics that work in both summer and winter. A casual chic style designed for men who prioritize quality over fashion trends. The colors available suit all styles. Timeless colors remain the most popular. Sizes from S to 6XL cover all male body types. The precise size guide offers the right T-shirt for every body type.
