Stamford Linen Blazer
There's a reason this one keeps showing up on "work capsule" lists: a revere collar, neat contrast piping and proper welt pockets give it the shape of something from Savile Row, while the actual construction is fully linen — recycled linen, no less — in a semi-fitted cut that won't wilt by lunchtime. Marked down by more than half, which isn't a sentence you often get to write about tailoring.
