When did everyone become so Victorian about showing some skin on the beach? In the 80's no one batted an eye if Magnum wore short shorts. Today fat ladies wear skimpy strings to the beach while the pot bellied husbands wear exaggerated pajama like board shorts that cover the ankles with cartoon characters printed all over them.
Careful don't show too much skin!
They should exchange swimwear.
