Trendy hairstyle feature to transgress? (8)

I believe the answer is:

infringe

I'm a little stuck... Click here to teach me more about this clue!

'transgress?' is the definition.
(I know that infringe is a type of breach)

'trendy hairstyle feature' is the wordplay.
'trendy' becomes 'in' ('in' can mean fashionable).
'hairstyle feature' becomes 'fringe' (I can't justify this - if you can you should give a lot more credence to this answer).
'in'+'fringe'='INFRINGE'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for infringe that I've seen before include "Encroach on (a right)" , "Break the rules" , "Transgress" , "Encroach, impinge" , "Neglect to obey" .)

I've seen this clue in the Sydney Morning Herald.
