It fit great glad I did size down like the reviews said. It's stretchy, the color is accurate and the fit is flattering. For reference I'm 5'2 @145 34DDD 34-33-44

This jumpsuit hugs your curves in all the right places. I would say it runs true to size. The strange thing is, the blue one has way more stretch than the black one. I bought both colors and when putting on the black one it was tighter on my calves and hugged my body more tightly than the blue one. The blue one still had plenty of room for me to move around in and probably will stretch out as I walk. They were the same size, so I'm unsure why the blue one fits looser. Medium is my normal size and that is what I purchased. For reference I'm 5'3 165 lbs 37 29 44 measurements. I'm curvy and this fit perfect for me. If you are thinner without the hips you could probably size down for a tighter fit. The jacket is a plus as well. It's a lightweight material, not see through. Perfect for weather wear it's warm and sunny in the day and cooler at night.
