If you've been single for 4 years and you've also had a dry patch that has lasted that long, I'd say you're not trying hard enough. If you like this sort of girl go to where they accumulate i.e. there's a rock festival in Camden tomorrow.

I have a very similar issue, my type of girl is a typical topshop girl: leather jacket and eyebrows like cara delevigne, and pretty decent banter. Now when I walk the streets realistically I'll find one or two who are my type and decent enough.

Buit that's just my ideal. There's loads of birds who you still find hot but don't hit your ideal. Try one of each once see if you like it. You can't just put yourself in a box, otherwise you won't do anything even if you see your ideal.
