Slim Fit is fitted closer to the body, without any excess fabric. Not too tight to be snug or restricting in any way, it is merely trim. Many different body types can benefit from this fit.
Modern Fit is a great choice for men who want something a little more fashion-forward than a Regular Fit. But in comparison to a Slim Fit would feel more comfortable with a little extra room.
Regular Fit is relaxed and easy to wear. It's cut generously through the chest and waist, but still maintains a clean silhouette.
