Well with ouges dresses, which i Love, i always order a size up. So i usually wear L in other brands, this one i ordered an XL, fits great and would be a favorite, but I have a 38C chest, and this DOES NOT cover them, I am spilling out. My husband's like "yeah they look great!" but as a woman, I am NOT going to go walking around with my boobs spilling out. Also it was tight in the armpits - not like my other XL ouges dresses.  there was major static cling, this is like a fake chiffon kind of material and it was bunching up all over me immediateley upon trying it on.  I would absolutely be in love with this dress bc the waistline is in a flattering place and minimizes a big hip or waist, so I wish they would make another version to cover up the chest just a little more. I love V necks bc for larger chests they are flattering, but this is not as pictured (maybe if you're an A or small end of B it could work for you.) I hope they try again on this one minus the static cling material and the chest problem.
