I ordered the "Dark Green" in a small and medium because I'm between sizes. First of all, the "Dark Green" is really a beautiful emerald green, not a forest green - I love it! Second, the fabric is super stretchy, which is both good and bad. Super stretchy = super comfy. But it also means it kind of loses shape as you wear it. I find that I have to keep adjusting it in the chest (I'm a little busty, so this may not be an issue if you're smaller up there); the weight of the skirt pulls everything down, and then the tank part of the dress gets stretched downward and hung up on my chest, so I have to pull it back up regularly. Not a huge deal, but a bit of an annoyance for me.Both the medium and large fit, but I ended up going with the large to make it a bit less clingy. Overall, this is a very flattering and comfortable dress! Looks great paired with a cardigan! I particularly like that the pleating goes all the way around the skirt, not just in the front; this is helpful for those of us who carry our weight in the hips/thighs/butt. Glad I listened to the positive reviews on this one!
