you need to grow it out and then get a side parting. decide which side looks/falls better and brush your fringe to that side. if your fringe is too large or falls in your eyes then split a small part...
If you want a side fringe or side swept bangs, you could go to your hair stylist. If you want a specific type of side fringe like a celebrity has, you could print out a picture of the celebrity...
See which side your hair naturally falls or bends. If its just straight down then you can put on any side. Another thing to check out is if you have any cowlicks that will disturb your fringe.
