white pants, uhhh, not to sound like hate - but you're gonna regret that in about a month. Trust me, I had a white Jacket and it's now a brown and red jacket (our rails are painted red).
Anyways, A lot of stuff goes with White, but probably the thing that goes best is black. I'd go with any dark colored Jacket (black, dark blue, dark purple, ect -whatever your steeze is).
