My measurements (cm) match a size L, however, I would size up if you want comfort. I will say the corset is pretty tight while people say, "Corsets are supposed to be." No, no, no. Corsets are supposed to fit to SHAPE the waist while hips are added to dresses lightly. That's how it's been, but dramas have gotten it confused. I was scared to rip any of the fabric because I could hear small tears. Not a fan of the zipper on the back. Would much prefer zipping from the side with a black zipper. I don't believe it would matter to have the zipper on the size as the back is supposed to be covered by the cape. I would say the cape and jewels are my favorite part of the costume. The jewels are shiny and match Raven well. The cape is well-done and drapes over nicely. Again, not complaining about the look, just the tightness. I'm not used to feeling so constricted. But it is a beautiful costume. I do recommend for photoshoots.
