Stick to shoes that are easy to lace or slip on, and pants and a top that are easy to take off on gym days. <sep> (A) [substeps] Gym classes always start with a gym uniform, and vice versa, so you'll want to wear more and less of these for each class. For example, you may wear a pair of jogging shorts for gym class. (B) You'll be able to get out of these clothes-and into your gym clothes-quickly. [substeps] For example, skirts with elastic bands, comfortable jeans, pullover shirts, and slip-on flats are great options for gym days. (C) [title] Make sure your locker is locked all the time and you cannot get in. [step] You'll be surprised how different locker rooms look. (D) [substeps] If you're at a new school, make sure to set the dress code. If you can, try to keep your clothing conservative or there won't be any nervousness or difficulty on gym day.
