Right, if you’re after that easy, thrown-on-but-still-chic vibe, this Theydon Overshirt is a solid choice. The subtle blue and stone check pattern is proper smart, so it works perfectly layered over a simple tee for when you want to look put-together without overthinking it. It’s got a relaxed fit, which is ideal, and all the practical bits like a six-button front, two chest pockets, and two more at the side. Plus, the classic button cuffs mean you can roll them up if you’re feeling it. It’s made in the UK too, so you know it’s decent quality and will actually last.
