The rib is the whole point of this one. Velvet Vogue worked a chunky vertical rib through the entire body and sleeves, which gives the jumper a column-like line and enough weight that it holds its shape rather than collapsing at the shoulder. A half zip opens into a tall fold-over collar, so you can zip it to the chin on a cold platform or drop it down and let the collar sit soft around the neck.

The fit is oversized rather than merely relaxed. The shoulder seam falls low on the arm, the sleeves run generous to a ribbed cuff, and the body has room through the waist before the ribbed hem draws it back in at the hip. It is unlined, which keeps it wearable indoors, and the rib means it layers over a shirt collar without looking bulky at the neck.

Three colourways are offered: Black, Apricot and Baby Blue, in sizes S to 2XL. Our model is 5'8" and wears a size S for the loose look shown, so take your usual size, or size down for a closer fit through the body. Wash it by hand or take it to a professional dry cleaner, then dry it flat so the rib does not drop.
