They call it the tights. Not as sheer as a panty hose, but not as thick as an ordinary leggings..
Actually... I do not know what is it!! Bought in H&M Berlin while doing a show. Every girl who wears a skirt have one of these as their second skin.. Used a pair and left with another pair of new ones. Extremely good quality since it's made in Italy. Originally Euro5.90 for 2 pair.
Size : M / L
Color : Black
Reasonably yours for RM 12
