I do too especially the underneath of a shiny tutu whwn the male dancer lifts the ballerina off her feet and you see the underside and those legs covered by the smooth pink tights and the feet in pink satin Pointe shoes.

Also I like them when my partner is wearing a shiny tutu in class and I get to move my hands up her legs and onto her lycra clad bottom.

seeing that makes me go stiff at the crotch, that is one of the reasons I took up Ballet
