Topman is your go-to destination for blazers that look vintage. Made from fabrics with a strong resemblance to tweed (and which sometimes are, in fact, made of tweed) they've also got contrasting lapels and elbow patches. Topman's got a lot of styles worth looking at, but try to avoid things like leather detailing and contrasting shoulder patches – they tend to look cheesy. If you want to keep it simple and a little trad, try the Grey Donegal Blazer, the Camel Checked Blazer, or the Harris Tweed Green Contrast Blazer. And if you're looking to step out a little, the Selected Homme Blazer is single-button, slim, and lightweight, while the Charcoal Cut and Sew Checked Blazer combines a bunch of different checks in a very compelling way.
