My team has the greatest uniforms is all of BB, which I can keep telling everybody since there are none here. If have to choose from a very limited number of types and trade in the ones that my team really has (since of course I fully believe that my team is a real team with real players), I won't have these bragging rights anymore.
If a team needs team colors and needs to show an image, the Supporter features are great for showing off your logo and team banner. You can always show a uniform in either of these places. Anyone looking at my team's page can get an idea of what my team's colors are. Supporter doesn't cost all that much and can add so much for your team.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
