Why can't you wear underwear under tights for ballet?

Tights are skin tight garment, they show your underwear when you are wearing underwear and show your butt when you are not. The only thing i think i can wear is a thong or a G-string and every time i wear them they give me a rash. I wanna know, do you have to clean your butt very well before putting on a thong or a G-string.

You're not supposed to wear underwear because it looks bad. It either hangs out from underneath or if you bunch it up it looks like a diaper. Just wear the tights and make sure you wash them well. It's part of being a dancer - get used to "going commando".

wearing underwear under your tights is bad. it affects your lines and is unhealthy. it can cause infections(i wont go into detail)

as for the rash. i had the problem with my dance belt causing it and it sucks. good luck figuring it out.
Ask your dance instructor these questions!!!!!!!!!!
you can wear underwear, ido
i don't understand why you can't wear underwear i always have and i didn't get rashes or anything like that and i have been dancing for 4 years
Yes personal hygene is very important if wearing a G-string. You can easily get a UTI if you're not clean. Wiping may be not good enough. Fresh out of the shower is more like it. Also find a different pair of strings - different brands are made differently, maybe there is a pair that fits your butt better.
First off, is this being asked by a guy cause if it is then you really dont know anything about dance, cause you would know that under your tights you wear a dance belt, and under that you would wear underwear. If this is a girl, who told you that you can not wear underwear under your tights and leotard, because who ever did is wrong, i have been in dance for years and have always worn underwear under my tights and leotards, and really asking if you should clean yourself well before putting on a g-string, what do you think the answer is? If you are a girl, you must always keep yourself clean, or you will end up with an infection, easy and simple. This is the type of question that you should be asking your instructor and parents.
I love seeing a female wearing just bra, panties and tights especially printed panties
