I tried this on using Prime Wardrobe. I'm normally a 22 pant and 2X top. I tried on the 2X, and it fit as expected. It's a very, very simple dress. Mostly comfortable, and the elastic waist was in the right spot. Thin material, but not see-through. I couldn't figure out what to do with the shoulders though. The neckline is elastic, so it sat funny when it was on my shoulders as in the pictures, so I tried it as an off-the-shoulder dress, but I didn't want an off-the-shoulder dress, and it didn't stay down very well. If it were patterned, I might have kept it, but as a little black dress, it just wasn't working for me. Way too casual. Would look better with a belt, I'm sure, but the neckline is what made me decide to return it.
