This is a vintage piece by Free People intimates in size medium, but it could fit a larger size as the back is stretchy. It’s very nice because it holds in the Tatas so you don’t have to wear a bra and the bottom half of the dress or slip is very lightweight. Not see through. I have worn this in the summer. I have worn this underneath my winter dresses and I have worn this to bed, so it’s very versatile. It’s very comfortable. It has frayed edges for that bohemian look the straps. Don’t really fall down at least on me and it has beautiful embroidery. I rarely wear this one so I am selling. I own all the colors 😂 The color of it is very strange so I see it as a purple gray but my husband says it’s gray, and the embroidery appears to be a deep navy blue if that helps any ask any questions if I could answer any already thank you
