I loveeeeeeee this dress it hugs your body like a glove .

I’m 5’9 with a 34DD and normally wear a small. I went with my sports bra size (medium) and it was a perfect fit. The bust has a thick padding so it gives you a built in bra plus push up. You can remove them. Shorts also attached and they are comfortable. I normally wear a small in dresses and tops that have stretch. But this is comfy and would be great if pregnant. Stick with your normal size if you want tight. The top fits smaller where the skirt is more looser with me sizing up. I bought it in white it’s sooo cute
