That's a good pickup. I'm not sure if Stewart's is a chain or there are just a few stores with the same name around Sydney; I know there's one in the MLC building and one on George St somewhere as well... D'Urban are good suits for the price. I know someone who swears by them, and they look well on him. Yours made in HK?
I have had D'Urban suits for years and they are great and fit Aussies well if that means anything. Stewarts is a tregualr menswear place.
