Okay, someone name me this plethora of teams that everyone is implying that have used "belt buckles" in their uniforms, 'cause I'm thinking Top Gun and that's it. Planet Cheer's looks a heck of a lot better than Top Gun's, let me say that much. Maybe if it spelled "Galaxy" there and not on the arm, I'd like it.
The only other thing I really don't like about it is the fact that it looks like a tank top over top of a normal uniform. Even just taking out those blue stripes around the white, taking the white to the collar and up would be better. I actually like the sleeves, oddly. A lot going on, but I like them. As for the logo, it can actually look good on a uniform. Take a look at their old uniforms (someone else can post a picture, I'm too lazy), it actually looked good, but that planet looks like a circle sticker with some small writing over top...
Ideally... Take out the white completely, make the front all black, write "PLANET" or "PLANET CHEER" in white outlined in blue, or the other way around, and take the logo off the uniform completely. It would look stupid to have the logo saying "Planet Cheer Allstars" when you already have "Planet" or "Planet Cheer" written on it. Also with the aforementioned "GALAXY" on the top of the shorts, not "PC"
