I am about 54 - 150 lb - 34C-D - carry most of my weight in my lower half & one year post baby and looking for an Easter dress that was flattering ;) This worked out perfect! I hover between a medium and a large - to avoid any tight fitting especially in my midsection. So I ordered both sizes (different prints) to try them on and see (thank you free returns!). And it turns out that the Medium fit better - there were not a ton of differences but I preferred the way the boat neck top fit better in the medium. I also purchased the knee length petticoat from the same company. It doesnt NEED it but it gave it that extra flare in my opinion. See my photos below for the different looks/sizing. I def recommend this dress & may even purchase other prints. ALSO this dress is much higher quality dress than I was expecting the fabric had a great feel too it, quality made. While I haven't washed the item yet, I did iron out all the wrinkles fairly easily!
