Sophie Organic Cotton Jumper, Cobalt White

The Sophie is the jumper that earns its place purely by being exactly what a summer jumper should be. White organic cotton in a delicate pointelle stitch—airy, light, properly breathable—with cobalt blue wavy stripes running across the body and cobalt ribbing at the round neck, cuffs and hem. There's a soft gather at the shoulders that gives it a gentle vintage quality without ever tipping into costume territory.

It's the kind of jumper that manages to look put-together even when you've grabbed it off the back of a chair at the last minute. And in 100% organic cotton, it's as comfortable to wear all day as it is easy on the conscience.

Lily & Me are a British brand with a distinct sensibility—cheerful, feminine, properly wearable—and the Sophie is very them. Cobalt and white is a pairing that works with everything from jeans to linen trousers to whatever you need to throw on in the evening when the temperature drops on a coastal walk.
