Astr the Label Pemberly Floral Ruffle Off the Shoulder High-Low Dress - size XS (sold out on Astr). Gorgeous dress, got so many compliments! Runs small, but super long. Probably closer to a 0 or 00. Side zipper. Worn twice. There was a tiny clasp held on by a thread on the lower part of the v-neckline that fell off when I first bought it and tried it on :/ (for ref I am a 32 A/B) however I did not end up needing the clasp at all; the straps are adjustable which helped the front not to sag or open up.
