For your consideration are a very unique pair of Spandex stretchy unlined panties for men
These are hipster style, designed for men not women (unless you like the front puffy) For the ideal fit your waist/hips should be somewhere in the middle of the range not at the beginning or the end
Note these only come in 2 Sizes because its is a different fit from the regular satin string bikini:
I do not have a very small one in this model, if you are petite these will not work for you.
S/M fits 24-40" waist (do not push it to the max)
L/XL fits 28-46"
