Runs EXTREMELY small
Color: Black-satin, Size: 3X-Large
Ordered a 3X but got a XS…i am a 42-44, got the 3X to have tapered to my fit, but upon opening the pants, it seemed they may be more of a 32-34 and the adjustable straps aren’t really adjustable, they are just buckles sewed in place for design. The 3X tag sewn in is a complete lie! Only giving 1 star because they did have the satin tuxedo stripe on the side!
