Gotstyle is at 62 Bathurst.
They carry a whole pile of stuff that would in no way match your mainline Zegna suits. Off the top of my head: T-Concept (Tombolini's Z Zegna), Cinque, Paul Betenley (sp?), Strellson, Ted Baker, Tiger of Sweden and the like. All slightly cheaper than the Boss's you find at Harry Rosen and of the same general quality construction wise. None of them worth the savings (if any) over Brooks Brothers or Samuelsohn in my opinion. I think Gotstyle is really oriented to the younger non-traditional guy who wants a suit that is cut very slim, but for whom quality is not really a primary concern.
Other than the Cerruti, Sand is the only thing priced a little higher than 1K at Gotstyle (as I remember). Their suits are a little on the wild side, and I've no sense of the quality. Seems a popular brand in the city though. The Coop carries truckloads of the stuff.
I was in a few of the Yonge street shops North of Eglinton recently (Jerome's, Ermanno, Coop, Testa Uomo). Ermanno carries a 1500$ range offering (Tombolini I think?). Testa Uomo seems to have a lot of Pal Zileri, and I assume at a similar price. Actually, Testa Uomo's new digs are really quite nice. I remember seeing Boss, Pal Zileri, Canali, Armani, Tombolini at the store when I dipped in quickly to escape the rain.
On a side note, has anyone checked out Stollery's recently? Is there anything there worth the visit? Last time I was there i was shown a Daks suit that looked to be about 10 years old... and a suit with the name Jaguar on it that I was assured was of the finest quality.
