This fully-lined maxi dress by Mara Hoffman Swim is made of a stretchy 92% modal and 8% elastane fabric. It slips on overhead, buttons at the nape of the neck, and has a keyhole opening below the button. The tag says Mara Hoffman Swim, which I guess means that this dress was made to be a swim coverup. However, I'm listing this as a regular dress, since I think it's absolutely gorgeous and shouldn't be limited to a few hours by the pool. I adore this dress and would keep it if I wasn't 5 feet tall. The dress is in excellent used condition with no flaws anywhere that I can find. The interior "Mara Hoffman Swim" label has come off on one side. You can easily get a needle and thread and re-attach it on that side if you want to make 100% sure that the label stays on. Please review the below measurements carefully to ensure it's a good fit for you. They were taken on the front of the dress with it laid flat. Please note that the dress is made of a VERY stretchy fabric, so can expand to accommodate somewhat larger dimensions as needed than the ones shown below.
