Unique yellow vintage style dress

I bought this dress from a boutique called Mintage and absolutely love it but unfortunately no longer fits me. It’s a mustard yellow colour with a light brown abstract design giving it a modern 70’s vibe. The dress has an elastic waistband and zipper down the front. The dress is in gently worn condition, the zipper and buttons are all well intact and there are no loose threads. The dress is a small but may also fit a smaller medium.
