Success, hint sent!

Say hello to Millie – your new go-to pair of trousers in classic black. Think Mabel's exagerrated barrel-leg shape, reimagined in a crisp, 100% cotton poplin for a more structured feel that keeps its shape all day long. Millie has a fly front, with a zip and buston fastening, four pockets – two at the side and two at the back – and an elasticated back for all day wear and ease.

Wash inside out gently at 30 degrees, wash with similar colours, reshape whilst damp if required, dry flat and do not tumble dry. Expect up to 5% shrinkage on the first few washes, reshaping whilst damp and ironing will help it bounce back.

Bust

Measure the bust line at the fullest part of your chest. Pull the tape as tight as you can without changing the shape of your breasts.

Waist

Wrap the measuring tape around your torso at the smallest part of your waist. Typically this is an inch or so above your belly button and is also known as the natural waistline.

Hips

Wrap the measuring tape around the widest part of the seat.
