This is where the benefits of dressing unique come into play. Don't need to wear anything wacky, but some lesser-seen patterns or colors, etc, can go a long way in regards to identification.
I don't even wear jerseys for recball. Name brand jerseys don't pop enough since anyone could buy & wear them, and custom team jerseys often sends the wrong message. So i've got 4 exclusive shirts, including a ninja turtle shell tshirt, red hibiscus aloha shirt, royal blue Davis PB tshirt, and a hazard orange long-sleeve i picked up for working a charity event.
I've also got a solid purple headband that has "Fat Boy" spelled across the tails. If that doesn't help, nothing will.
