I wear flared yoga pants, and a comfortable shirt either long or short sleeve. Sometimes I wear my jogging pants which are snug all over and don't ride up when our legs go in the air!
The main thing is to have clothing that moves with you and is comfortable. One woman comes in jeans, another in shorts, no matter what the weather!
But I also wear whimsical, bright colored knee high socks! I win the sock contest each week! I have fun with it and get them from "lil mismatched".
