retruns not free despite being labelled as such.
waist fine. length...rediculously long, thigh and calf stupidly narrow for larger sizes. also, despit it claiming that it offers free returns, they evidently charge something like $4? i dont know yet as they dont say exactly how much, but rather that it will be deducted from the refund. very deceptive.
