I have had these excellent Calvin Klein (CK ONE) hip brief tighty whities for many many years and they still fit and feel great.
I’m pretty sure I bought them on-line from Macys years ago. They are a little snug, but they are microfiber so they’re stretchy and non-constricting. I like pulling them out once in a while and wearing them…definitely make me feel sexy.
And just look at that cool “Boycott Pants” shirt I’m wearing with ’em. I got that shirt from Amazon if memory serves.
