Zach Uttich is a man who knows his suits. From the time he started reading his mother’s Vanity Fair magazines as a child, he became enthralled with tailored clothing. Fast forward a couple decades, after successful stints at places like Mark Shale and Suit Supply, he went out on his own to open his West Loop suit shop, which offers custom suiting, jackets, trousers, shirts and waistcoats in fabrics from Loro Piana, Ermenegildo Zegna, Thomas Mason, Vitale Barberis Canonico, E. Thomas, Reda, Albiate, Delfino, Distef & Quaregna. Custom two-piece suits start at $750, shirts at $165. By appointment only.
