Yesterday I went to Milan, the city of fashion, for shopping. 
If you love fashion and you are Milan, you have to check out the following shops:

For Vintage fans:
Milan is a real paradise for Vintage lovers. There are tons of Vintage and second-hand shops. 
Especially the Via Gian Giacomo Mora is filled with cool shops.

This historical milanese boutique has 3 stores in Milan. 2 for women and 1 for men. In all of their shops you can find a lot of antique accessories, hats, dresses, coats,bags and a lot more unique items. The prices are set pretty high, because they have lot of famous brand items.

For stylish bookworms:

There are quite a lot bookshops in Milan. 
One of the coolest is certainly:

Corso Como Bookshop (Corso Como 10)

This shop is pretty hard to find. It is hidden in an old house on the Corso Como. 
Anyway this shop is always worth a visit. You can find new and classic publications of art, architecture, design and fashion. Next to the bookstore, there is currently an exhibition  of the famous fashion photographer Arthur Elgort. Take a look at his awesome photographs.
