Russian Beaches I Need To Know How To Say "You Are Not Allowed To Wear Thong Bikini Bottom At Our Pool" In Russian. Help?

I need to know how to say "You are not allowed to wear thong bikini bottom at our pool" in Russian. Help? - russian beaches

I work in a community of apartments on the beach and the Russians have to stay here on a work program. They speak little English and I teach one of the girls are not allowed to wear the belt of the pool. Please can someone translate this for me? "You are not authorized to wear Thong Fund to the pool."
