Fitted fit tshirt aren’t always easy to find, especially if you have a big chest or are athletic. But a good fit is a vital part of any outfit.

If you want to feel comfortable and confident in your own skin, a great fit can help you achieve it. Here are some things to keep in mind when choosing a fit tshirt:

Look for a t-shirt that is snug but not tight. Too tight will cause it to ride up on your shoulders and emphasize your biceps. If it’s too loose, it will cling to your body and make you feel uncomfortable.

Try the t-shirt on in different positions, like at the waist and crotch. If the seams fall on your traps towards your neck, that’s a sign it’s too big and needs to go a size down.

You’ll also want the shoulder seams to line up with your actual shoulder bone. If it doesn’t, the shirt is probably too small and you might want to go a size up for a more slim fit.

A good fit t-shirt has a flat, straight neckline that won’t dig in or show chest hair unless you choose a v-neck. A v-neck isn’t a must, but it can add an extra layer to a casual look.

The best workout tees aren’t just made for exercise, they’re also ideal for lounging or running errands. Some top brands, such as Lululemon, even offer men’s t-shirts designed to wick sweat and fight off BO (a buildup of body odor).
