Don’t wear clothes that don’t fit. Tighter clothes don’t make you look smaller. On the other hand, if you’re a XL, wear a XL, not XXL. Even if you are conscious of your size, wearing the wrong size of clothes can make you appear larger than you really are. This includes workout wear as well. If you wear clothes that fit now, and tweak your lifestyle for the better, you get to go shopping for a size smaller, later!
