More combat clothes. Preferably street-combat clothes. Hoodies and t-shirts with bulletproof vests, skinnies and jeans with holsters, stuff like that. I'd use the Future Soldier and Young Soldier set pieces in SR TT but they were made into full-body suits in SR IV.
Besides that, masks would be nice. Not Halloween masks, we got plenty of those, but robber masks, or masked hoods, that sort of thing.
Generally stuff that doesn't scream "I'm wacky!". There's nothing wrong with that stuff but we're kind of swimming in it...
