I'm 5'11'' and height is not an issue with this dress. I got a size 12 because my bust is a 40 but waist and hips are smaller than the measurements for the 12 so that might need to be taken in. But that's my own fault for not getting the custom sizing.
Also, I ordered the dress in the colour Jade and I found it wasn't like it was on the screen and was more green than blue (although isn't jade a type of green?). The imagine on the screen seemed to be more of a light blue.
Lastly, the lining on the inside is very green compared to the rest of the dress, not that you can see the liner.
I'm giving it a 4/5 because of the liner colour, the colour wasn't similar to the one on the screen, and the zipper is also very hard to pull over a section.
