Istanbul is an enormous city with more than 18 milion habitants.For that reason it's more than logic , that there is a mosaic of different trends.
It's very amusing and funny as you can predict what kind of life and hobbies do people have , judging them from their dresses:)
E.g , the teenagers love to wear short trousers and short jackets.Minimalist and modern girlies , prefer skinny jeans a lot.
The punks like to act like freaks.I have to say s.t here: the true punks with style have really "gusto" and I like their look.But the ones who pretend being punks , just suck .Their looks are so comic and ordinary and their dresses , not creative at all.I mean you can't pretend to reflect the punk image when you even don't perceive the vision of that concept.
I mostly love the ones that dwell in retros and vintage as their dresses are really stellar.They're mostly well educated girls/boys, with high incomes and a good carriers , mostly doing arts.
Of course like with the fake punkists ,there's their fake wanna-be version , that would stir up your stomachs ...
Anyway if you wanna own a true original wardrobe and of course if you are a style owner:) there're plenty possibilities for you.Especially these last years a lot of private boutiques with cool , special designs have been opened.You can find retro, vintage garment boutiques and the best part is that they mostly produce unique dresses.That saves you from the nightmare of facing hundreds of people wearing the same dress , you've bought and you're dying for:)
Also there are a lot of warehouses where you can find really trendy things with reasonable prices.
Here there are some sites addresses for your reference:

and so on... Hope you'll enjoy it!
