Agreed, i dont understand why anyone would be asked to leave for wearing shorts simply because theyre female?! I figure you can wear what you like aslong as its not hazardous or see thru!
Ive just started swimming at the pool at the gym i go to, theres younger ladies that wear shorts & tshirts over their swimsuits for privacy. Youve got a right to wear whatever you want!
An i too was worried about my scars, the worst ones are on my upper legs an theyre still pretty red and obvious, once or twice people have noticed them but its not so bad, ive generally found people are more wrapped up in what theyre doing with themselves. Its more of a bigger issue to us.
I hope you go, and enjoy it. Its fantastic excercise and can be quite relaxing. Go for it
