usually u should wear what is combfortable to u and doesnt affect your game! i wear an arm band on my left hand {im right handed} and i wear an ankle brace

one game i wore a headband, got a lot of feedback from that, but usually i wear a wristband and a short sleeved under armour heat gear shirt underneath. and i wear a knee sleeve and nike elites or jordan socks

I think you should only wear accessories that help you if you're hurt.
