The stock patterns for ZB could probably pass for slim by western standards, but if you're used to the asian sizes that dominate most high-end leather it'll definitely be roomy. He can do MTM sizing within reason though if you contact him directly (SZ is best for this - he posts a lot there). I have one of his jackets from this season. I wouldn't put it up there with something like Julius, but it's solid workmanship and there isn't any real price markup based on "vision" a la something like Obscur or Rick. Also he's a pretty chill dude. If you like some of his stuff I say go for it.
