I want to wear nylons to my dance class - would this be ok?

I normally wear 30denier tights, shimmer tights or capri leggings - but i feel its time to wear decent sheers. I wear them almost all the time now anyway and the others know i cross-dress (turned up in culottes t'other day) What do people think? I used to wear black sheers when i was 19 or so - older now!
