NWOT prima Donna bathing suit UK 38/ EU 85

Army green. New without tags (still has sticker in crotch). Army green with black. Very flattering! Size EU 85 (which per size charts is a 6 in US but I would say this would fit a size 8). In a 6 and it’s a little too big (doesn’t suck me in). I entered size 8 on poshmark; the bathing suit does not indicate size 8
