How it fits

Small Just Right Big

Fit:

Petite fit: Designed for women 5ft 3 and under

Model: Model is 176.5cm and wearing a size UK 8 Garment length: cm 151.1 cm

Region:

1. Neckline

Measure the distance between the centre of your collarbones and the tip of the V-neck. We have 3 signature V-neck shapes: modest (17cm, bra friendly + suitable for bigger busts), classic (19cm, bra friendly) and deep (22cm, designed to be worn without a bra).

2. Garment length: dresses, tops, coats and jackets

Hang tape measure from the point where you neck meets your shoulder.

3. Chest (Bust)

Measure around the bust at the fullest part, whilst wearing the bra you would wear under the garment. Ensure you don’t pull too tightly.

4. Waist

Measure around your natural waist (typically the narrowest part of your torso, just below your rib cage) to measure circumference.

5. Hips

Measure around the broadest point of your hips (without wearing shapewear, even if you would whilst wearing the garment), ensuring the tape measure is level the whole way round.
