Strapless floral dress size medium

I bought this dress from wanelo. I've only worn it a few times so it's in very good condition. It's strapless and there's push-up/built in bra in the white top of the dress. The bottom is flowy with a floral pattern on the top and a slip underneath. The dress falls a little bit above mid-thigh. The majority of the dress is mint green with a white top and a blue/red/orange floral design. The dress doesn't have a size tag in it but it's a size medium.
