H&M Open Back Dress with Dots NWOT

Reposhing this item! It's such a beautiful dress, but unfortunately is a little small on me. It was NWOT when I purchased and I have never worn it. Original posher said there are a few tiny marks just below the neckline (captured in last photo). Midi dress in an airy, patterned viscose weave with 3/4-length sleeves, a seam under the bust and a deep opening with a covered button at the back of the neck. Concealed zip with a hook-and-eye fastener at the bottom of the back and a wide skirt.
