I saw this at the store today and the iridescent zipper is amazing. I took my usual size 2 in Scuba Hoodies. The fit is very slim and the feel is slightly stiff but doesn't feel restrictive. This is my first time uploading a video to my blog. I hope it works! I tried to take a video of how the zipper changes colors as you move. It's really very pretty. I left it at the store, but now I'm totally regretting not buying it!
