Feather And Pearl Lingerie Set

nwot bought from a bridal boutique a couple years ago, only tried on and has sat in my closet ever since, I didn't like the way it fit me and couldn't return. bra is 36B, unlined, with underwire. underwear are lace/mesh, full coverage, extra high waist, waist measures 10.5' (say size L but is European sizing, would best fit a s/m)
