Same as the previous reviewer. I got my true to size (8) and it fits tight. The front bottom of the shirt does bunch up slightly but if you’re wearing high-waisted pant/skirt/short, it shouldn’t be an issue. I would say go a size up. I don’t mind the tightness and it might loosen as I wear it. I mainly bought this to fit underneath a bodysuit.

This top is cute! I don't know if I agree with the recommendation to size down. I know this is supposed to fit tightly, but when I sized down (from a 14 to a 12) it got pretty short/cropped with the bottom hem rolling up slightly and the front seam pulled into a wave rather than straight down. I'm exchanging for a 14 and I hope that'll fit better, or at least, less weirdly. On the upside, the mesh is super soft and nice. I look forward to layering this in the LA winter to feel ~wintry~ without actually being too warm.
