I'd be concerned with the white being see-through when it gets wet. Although, are women even allowed to go swimming? Or is that too much for the menfolk to handle?
obviously some people also had issues with it not being modest enough-
"Love the lightweight material and length is just perfect. The neckline is a bit low, so will definitely need a bathing suit top underneath, but a great suit nonetheless."
there was no mention of armpit, however I assume a sleeved bathing top underneath the suit would deal with both the "plunging neckline" and armpit issue.
Perhaps some matching swim socklets would solve the ankle exposure problem?
