WHBM sequin jacket/cardigan

Condition: good Info: White House Black Market white/ivory sequin zip-up jacket or cardigan. Trim is ribbed sweater material, 3/4 sleeves. 70% rayon 30% nylon. Hand wash or dry clean. Top of shoulder to bottom hem approx 21", armpit to armpit approx 17". Story: Bought on Poshmark because it's so pretty, but not sure it even still fits. It's an XS so I'm going to say that's a no, although it does have some stretch to it. I haven't noticed any missing sequins. The sequins cover the entire jacket except the trim.
