If you want to have your butt and hips properly covered when you are wearing skirts, Boyshots is the best solution for you
Modeled after men’s briefs, they take on a more rectangular shape than most panties probably the most modest option available. They feature a thong-style base but frame the whole bottom with full coverage on the sides and front.
If you want to have your butt and hips properly covered when you are wearing skirts, dresses or anything with a flowy construction, then boy shorts would be your best bet. Plus, it’s less embarrassing if you happen to be having a Marilyn Monroe moment, because it will look like a pair of hot pants or ‘safety shorts’.
