Die.

White people with dreadlocks look stupid. It just looks like you want to be those monster things from Star Wars. They also make everyone assume you live in a box.

Ripped jeans. Only IDIOTS would buy pre-ripped jeans. What person would pay more to have their jeans ripped for them whilst all you need is a pair of scissors. Skinny jeans with rips and tears in them look decent, however when bootcut gets involves it looks as though theres been a fight between Atomic Kitten and B*Witched.
Fake Marc Jabobs stam bags. They look cheap, tacky and everyone know you can pick them up for £10 from those crappy Oxford street handbag stalls. About 27389127812% of the British population has them so you're not fooling anyone that it's real-To be honest, it's not even worth owning the real ones, as you'll be about £400 down and it's not that much better. Plus "it" bags are out, I gladly open the "it" scarves with welcome arms.

WHY IN THE NAME OF GOD WOULD ANYBODY EVER BUT THESE THINGS??? Full-sized Ugg boots make me dry-heave already but these things make me just kill my faith in humanity. They look like they've been made by a blind child with too much spare time. Yes, they may be comfy but is it really worth forking out £100 just to make you look like a slightly deformed hobbit? No.
I'm hoping they'll die out forever like I think they will at the end of every winter. Personally I blame Primark and sloanes for these things being reproduced from people's cupboards every winter.
