Don't rock swim trunks. The elastic hem is not your best friend. Consider a proper pair of board shorts with a longer inseam around 7 or 9 inches. Make sure they still hit just above the knee so you don't look like you still live in the '90s. Keep the rise regular too, that way your boardshorts will be more flattering and draw the attention away from your stomach.
