What do I wear underneath to a uv paint party So it doesn't show underneath?

I'm going to a uv paint party and the sign says to wear white but I heard that sometimes bras and underwear will show through? If I wear a beige bra and thong will this show through? Or what do I wear. I have a old white cute Tank top im wearing with a pair of white jeans or Jean shorts. What colour is best for thongs and bras not to show? Will Beige work?
