No, a fringe isn't old fashioned, but be careful with it because if you've gained a wee bit of weight on your face, it might make your face look more round that it really is.
My face isn't fat, but having a fringe makes it look round so I settled for one that sweeps to the left.
Have you got magazines lying around? Have a look at all the models in the adverts, see what their styles are like, invest in a couple of hair mags too. Go to a good hairdresser and ask their opinion too.
The main question is do YOU want your fringe back??
