Go for what you like personally . Trends may come and go but if you choose what you like and are into then you develop your own sense of taste .
Example : Trends of the moment / dark black goth looks , grunge , etc.
Lulu likes to wear vintage clothes and want to dress like her style icon Audrey Hepburn .
Remember trends die out quickly . Don't feel pushed or pressured into following someone else's
idea of style and fashion even if they say that is a fashion don't . Be comfortable with yourself and then your true sense of personal style will come through .
