I dunno. I'm gonna call

on their reaction.
I'm a gymnast parent. My daughter and her teammates spend 4.5 hours at a time working out in gymnastics leotards which make the 'bloomers' I've seen on any cheerleader seem puritan by comparison,.. and they don't wear any skirts to feign modesty.
Couple that with the propensity of 'Gap', 'Justice', and any number of other fashion outlets to peddle sweatpants that have words emblazoned about the tush such as 'Pink' .. Gymnast... Tumble.. Abercrombie.. Old Navy.. etc ad nausem.
Unless the cheerleading undergarments in other parts of the country differ greatly than what I'm accustomed, I think anybody getting bent out of shape by cheerleaders exposing their uniform 'underwear' is just blowing smoke to be seen.
