The Ultimate Guide to the Overshirt

Every guy needs an overshirt, its a throw on classic. The overshirt is the hardest-working layering piece in a modern man’s wardrobe.

Wear it buttoned up, open over a tee, layered under a coat, or even as your main outerwear in transitional weather. Here’s everything you need to know about overshirts—how to wear them, what to look for, and where to buy the best ones. And with tellar.co.uk, you’ll get the fit right across all brands.
