I am 5'5 167 with 36DD and I got a size large! I love this jumper. It is comfortable and fits great. It shows a little bit of cleavage but, not so much that I feel I can't wear it anywhere. I just ordered a second color. This is my first one piece jumper and it is a win!

Love this jumpsuit! The material is soft (think supersoft t-shirt), lightweight, and thin without being see-though.
I felt like it did a great job of hiding my insecurities, and it was comfortable and flattering. Very easy to get on and off for going to the restroom.
For reference, I got a XXL, I am 5'3\\\" 230 lbs. I wear a size 20 in most pants and dresses and am a 36F bra.

Got so many compliments!! Such a simple outfit but super cute! Dress it up with a belt and jewelry and its a great look. I bought a large, I'm usually an 8-10 and it was a perfect fit. It was true to the color. Thinking of ordering in a different color.
