You can wear shorts, you can wear bathing suits, you can wear tank tops. You can wear ANYTHING you want to regardless of body size, shape, scars, veins, tattoos, hair, bumps, stretch marks, etc.
I first posted this image in the middle of Summer when it was more common to wear more revealing clothing due to the hot temperatures, however it applies all year round. Wear whatever makes you feel comfortable and confident and your best. Wear what allows you to move in the ways you want to move. Wear the colors, shapes, and patterns you like.
