All of these are in Steve's book
For streetwear. Diesel on Rush, two blocks off Mich.
Apartment No. 9 in Bucktown- Paul Smith and a great selection of hand picked designer goods.
Also have to stop by Barney's New York on Oak and Rush.
For Dior Homme (only one in Chi), Yohji, Kiton, Zegna, Massimo Bizzochi, Lorenzini and Chrome Hearts you must go to George Greene. It's not cheap, but my favorite after Steve pointed it out to me. On Oak just down the street from Barney's...
