That swimsuit looks tricky to put on and take off. She wears it very well though.
She had a bathing suit on ?
Calling that get-up a “swim” suit is a bit of a stretch. No way did the stringer have swimming in mind. Looks more like a cat’s cradle to me: jerk the strings and watch the button in the middle spin? I guess you’d buy one by the foot/yard/skein?
