Fit is the most important part of choosing good clothes. Based on knowing your body proportions, generally speaking, clothes that fit well should be comfortable, not impede your movement, not too restrictive, and also make the whole person's body proportions well coordinated, while at the same time not looking too baggy or sloppy. If you're planning to lose weight, don't buy clothes that you think you'll be able to wear in a few months. Instead, hold off on buying major items until you make any major changes, and wait until you have successfully lost weight before buying clothes that fit you according to your post-workout body to get better results. Again remember to always hem your pants, especially if you are on the short side. A hem that is too low will make you look even shorter.
