There are certain parameters to be kept in mind while choosing a T-shirt. These are:

Elegance is always in style for men. There are all different kinds of elegance. It can be silk, it can be a T-shirt.

Fit: The right fit is as important in a T-shirt as it is in any other clothing.

• Size- A well fitted T-shirt means that it should neither be too tight or too loose. If you have a good physique you can opt for a T-shirt that is on the tighter side. If your belly shows, then you should go for a slightly loose fit T-shirt that covers your curves , thus making you look less bulky.
• Length- A ideal length of the T-shirt should be a few inches below your waistband. The bottom hem of the tee should not be higher than your hip. It looks smart this way.
•  Sleeves- The sleeves of your T-shirt should fall halfway up above the upper arm. In case you are quite tall, it can fall a little farther down.
• Shoulder seams- The shoulder seams of the tee should be perfectly aligned with the end of your shoulders.
• Shape- A boxy cut T-shirt will make you look more sloppy than smart. Choose one that follows the shape of your body a little.

Collar/Neckline: T-shirt come in two necklines- the V neck and the crew neck. The crew neck is the most classic one, and is well suited to people having a long neck and a slight build and frame. A V neck imparts more style to a T-shirt and has a less formal feel. It looks good on men with broader or rounder faces.

Color/Pattern/ Design: T-shirts in basic colours like white, black, grey and navy look classic and can be teamed with other pieces easily. Pocketed and striped tees also look good and add variety to your collection. To get a younger and cool look, opt for graphic tees.

Material : T-shirt made out of 100% cotton are more comfortable and look good. For workouts, opt for tees made from special synthetic fabrics.
