New without tags (only tried on)

H&M (still in stores ) black & white zig zag stripe tunic dress .. wide sleeves (which are not full length) and a twist detail to the front

Size S but quite oversized (fits me and I’m a 12 so I’d say size 12 or smaller )

Measures 19 inches across pit to pit and 34 inches long from shoulder to hem

Pet & smoke free home
