For a jacket get the DNA judge harm. Even though it's last years it still looks pretty sweet and goes for $193 on www.jibij.com
I don't really know of alot of white pants , but I think you should go with the new siver tactical pants and they are $160. If you look on the front page you can find them on the siver preview. You might also be able to get them on jibij or d-structure. Overall this is quite an affordable and durable setup.
