Adorable black peplum dress

Absolutely love this dress. Just received it in the mail today (it was a Poshmark order) and tried it on. My husband and I agreed that I need one size bigger. It is a MEDIUM but runs like a SMALL. The seller said so in her listing, but I thought I'd still try it. Definitely fits small. So sad to part with it so soon, but I hope someone will be able to wear it and enjoy it!
