This is a thick and fitted sweater dress that is so pretty. Size down for a tighter bodycon fit. This dress is true to size if you’re taller than 5’4. The zipper in the back was like a mini rollercoaster on me and I got the zipper altered. (You can cut the threads around the zipper so that they don’t get stuck.) With all that said, I love how this looks on me and I can’t wait to wear it! You can wear medium compression shapewear. I’m 5’4 and this is floor length.
