Should i wear sweats during warm up for a dance class?

For ballet you want to wear tight fitted clothing like maybe a leotard and tights because if you wear baggy clothes like sweats then the instructor can't see your form and technique so it would make it more difficult for him/her to correct you. And for tap and jazz, i think as long as your comfortable then its ok. But for tap, make sure your sweats don't cover your feet or ankles because then you'll find it hard to tap and the teacher will find it hard to see your feet.
