Hello Eve
and a big thank you to Jared! That was really funny
If you didn’t think that half the battle was controlling your mind, you do now 
Yes Eve, we could start out by saying don’t wear jeans. Really you should avoid sleeves, long pants, anything that is baggy. Clothing like that tends to stick when you sweat and doesn’t move with the body.
I think the best thing to wear is stuff that moves with you, is a skin fit and wicks the sweat away from the body (plenty of wonderful modern fabrics available): gym gear, bike shorts, or capri pants (although you will cool down better in above the knee shorts).
Tops should be sleeveless. You can choose crop or singlet style tops. Once again you may feel cooler in crop tops.
Just a little note: not too skimpy, and nothing you need to do modesty checks on!!!
Enjoy your practice
