What color shirt and pants?

So I have this light light almost white/ gray aerpostale jacket and I have these brown vans. So I want to know to know what color shirt and pants I should wear. I am a guitarist in a band and were gonna be doing a gig so I want to look nice. If it helps also take into consideration that my guitar is black. And should I wear a shirt that is one color or are design fine too? For pants I only right now have these two pairs of blue jean, but I have other color pants too. And I think the lighting is a little dark and there are no color lights.
