Choosing your size
- Tops and knitwear: choose by your bust measurement. Relaxed and oversized knits can be worn in your usual size.
- Coats and jackets: if you plan to wear a chunky jumper underneath, or you are between sizes, choose the larger size.
- Biker and faux leather jackets are cut close to the body and do not stretch. Between sizes, size up.
- Jumpsuits and co-ords: check both bust and hip, and choose the larger of the two sizes.
How to measure
- Bust – around the fullest part, keeping the tape level across your back.
- Waist – around the narrowest part, usually just above the belly button.
- Hip – around the fullest part of your hips and bottom.

Description
The short trench
Every trench detail, cut to the hip.
A tall funnel collar that buttons to the chin, a double-breasted front and a tie belt to pull it in at the waist. It stops at the hip, so it works as easily over wide trousers as over a midi dress.
Why you'll love it
- The collar: tall and funnel-shaped; button it up or fold it open
- The front: double-breasted, with shoulder epaulettes and button sleeve tabs
- The waist: a self-tie belt that shapes the jacket
- The length: hip length, with a soft flare below the belt
