I typically wear a 6-8, so I went with the 8 since I am 7 months pregnant. I didn't get the back-up size (it came back damaged), so thankfully the 8 worked out just fine! The back is low enough to be elegant but high enough that I could wear a regular bra with it, which was an added bonus in my opinion. A lot of dresses that aren't specifically maternity dresses ride up in the front due to the belly size, but this sat nicely. I'm sure it's a great non-prego dress, but for being pregnant and not wanting to look like a circus tent, this certainly fit the bill!
