Cosy and street stylish at the same time, which shouldn’t be possible.

Why it earns its wardrobe spot
Anything that screams cosy has my attention, and an oversized button-down cardigan is about as cosy as knitwear gets without turning into a dressing gown. The volume is the point: it’s meant to swamp you slightly, which is what makes it comfortable rather than shapeless.
Worn over jeans it reads relaxed. Worn with comfy trousers and a bralet underneath it turns into something closer to street style, which is a lot of range for one piece of knitwear. Buttons give you a closed version for a cold morning and an open one for everything else, so it covers more of the year than a jumper does.
WHO WEARS THIS
For the days when comfortable and put-together need to be the same outfit.
The Woman Who Dresses for Comfort First: She’s not compromising on cosy. This is the version that still looks considered when she leaves the house.
The Oversized Silhouette Fan: Volume on top, something fitted underneath. A shape she already knows works for her.
The Person Who Lives in Knitwear from October: One cardigan doing five days a week is a reasonable ask if it’s the right one.
The Layerer With a Cold House: Buttoned up at breakfast, open by lunch. It handles a badly heated flat better than a jumper can.
