I actually really like these. I'm a big fan of white or light coloured uniforms because I think they really stand out on the mat and look cleaner than black uniforms, and the design of these is pretty well balanced. There aren't jewels thrown haphazardly across the uniform, and I like the shoulder and neck cutouts.
But onto the back...
I'm not crazy about the back, but it's not a total deal breaker for me. In fact, if the black bands on the top and bottom were thicker, I would actually like the back. My issue isn't the strappy back (I like strappy backs or back cutouts), but the fact that the straps take up too much of the back. It doesn't look like a cutout with straps, it looks like the thin straps are holding together the uniform.
overall I'd say it's a decent uniform, and with a few changes it could be very good.
