To refine your choice of fabric and style, it is essential to explore targeted collections according to your daily needs. For example, you can discover the best men's shirts to quickly identify the most versatile models.

Depending on your style, opt for men's plaid shirts for an authentic casual look, men's casual shirts for everyday comfort, or even men's cotton shirts favoring breathability and softness. Finally, the men's work shirts offer an ideal solution to combine durability and professional elegance.

Why is a good shirt fit essential?

A shirt A poorly fitted shirt can ruin an entire outfit. Too tight, it pulls on the buttons and restricts your movements. Too loose, it creates wrinkles and looks sloppy. According to recent studies on French body shapes (National Measurement Campaign CNM 2025 by IFTH), bodies are evolving: men have gained on average about 3 cm in height and 2 cm in waist circumference since the 2000s.. These changes explain why many standard shirts no longer fit as well as before.

A perfect fit not only improves comfort but also confidence. You move freely, and your outfit stays impeccable all day. We regularly see with our customers: a well-chosen shirt transforms the overall appearance.

How to take your measurements before buying?

The basics remain simple: measure your body with a tape measure. Ask for help if possible for more accuracy.

• Neck circumference : Place the tape measure around the neck, under the Adam's apple, sliding a finger for comfort. This is the key measurement for formal shirts.
• Chest circumference : Measure at the widest point, under the armpits.
• Waist circumference : At the level of the navel.
• Shoulders : From one shoulder bone to the other.
• Sleeve length : From the center of the back (nape) to the wrist, with the arm slightly bent.

Compare these figures with the manufacturer's size charts. Many brands, including ours, offer detailed online guides.

Here is an example of an approximate size chart for men (based on recent standards):

These values vary slightly depending on the fit (slim, classic). Always check the specific guide.

Key points to check the fit of a shirt

Put on the shirt and button it up. Observe yourself in a mirror from different angles, moving.

1. The collar

The collar should allow you to easily slide two fingers between the fabric and your neck. Too tight, it marks the skin and hinders breathing. Too loose, it gaps and looks slack. This detail matters greatly for daily comfort.

2. The shoulders

The shoulder seam should fall exactly on your shoulder bone. If it drops onto the arm, the shirt is too big. If it rises toward the neck, it is too small. The shoulders form the "hanger" of the shirt: everything else depends on it.

3. The chest and torso

Pinch about 2 to 5 cm of fabric on each side under the armpits. The shirt should follow your shape without pulling at the buttons (no "X" effect between buttons). When raising your arms, you should not feel excessive tension.

4. The sleeves and cuffs

The sleeves follow the arm without billowing or tightening. The cuff reaches about 2 cm above the base of the thumb, arm relaxed. With a jacket, a bit of cuff should show. The cuff buttons stay closed without forcing.

5. The length

For a shirt to be tucked into pants, it should cover your buttocks and stay in place when you raise your arms. Too short, it constantly comes out. Too long, it creates bunching.

Test by sitting and moving: everything should remain comfortable and in place.

We often recommend choosing a size based on the shoulders, then adjusting the rest if needed (alterations possible at a tailor).

The different types of fits and their characteristics

• Slim fit : Follows the body closely. Ideal for slim figures, but check comfort at the shoulders and chest.
• Classic fit (regular) : More ease, comfortable for most body types.
• Loose fit : For a casual style or stronger body types.

According to recent data, many men opt for a balance between fit and comfort due to changes in waist measurements.

Additional tips for a successful choice

• Always try the shirt with the clothes you will wear (pants, jacket).
• Look at the back: no horizontal wrinkles at the shoulders or back.
• Consider the fabric: cotton relaxes slightly after washing.
• For larger sizes or specific body shapes, custom options avoid many disappointments.

FAQ

How to correctly measure your neck size for a shirt?

Place the measuring tape around the neck, just below the Adam's apple, leaving one finger's width for comfort. Round up to the nearest half centimeter. This measurement guides the choice of the main size.

What is the difference between slim fit and classic fit?

The slim fit hugs the body more for a modern, sleek look. The classic fit offers more volume and comfort, suitable for extended wear or different body types.

Can a shirt that is too large be adjusted?

Yes, a good tailor can alter the sides, sleeves, or length. Shoulders are still difficult to modify, so it's important to check them carefully first.

How do you know if the sleeves are the right length?

With arms at your sides, the sleeve should end near the base of the thumb. With a jacket, about 1 cm of cuff ideally shows. Test by moving your arms.

Should the material be considered when choosing a size?

Absolutely. Stretch fabrics tolerate a closer fit. Pure cotton may shrink slightly when washed: follow the care instructions.

Can a shirt be perfect without trying it on?

It's possible with precise measurements and a reliable size guide, especially for custom models. However, trying on remains the best final check.
