There should be some pictures of the IRI T-shirt quilts around CD-Media. Those have a pretty good sampling of team shirts. (You could also search CD-Media with the term "T-shirt" and see what comes up between the T-shirt cannon pictures.)

There are a few tendencies that I've noticed in the teams that wear T-shirts:

Team T-shirts tend to have the team logo (front and possibly a smaller one on the back) and a list of sponsors (back). If the logo doesn't include a number, the team number is typically placed somewhere on the shirt. Sometimes teams also put the FIRST logo on their shirts; be sure to review the logo guidelines if you go that route.

The worst team shirts I've seen were the ones where it looked like the instructions were, "Go get a white T-shirt and mark it with team identifiers." Those students didn't look much like they belonged together; a common shirt really helps show who goes with which team.

If, for some reason, you can't get a custom team T-shirt (cost is typically around $10 apiece), then your next-best bet is to choose a team uniform so that everyone matches, and so that you look reasonably professional, and go with that.
