Materials, sizing and care
Materials, sizing and care
Materials
The materials for this item are listed in the specifications above. Knitwear may be a wool blend, cotton blend or acrylic; outerwear may be padded, waxed cotton, denim or fleece; footwear may be genuine leather, suede or man-made materials — we say which on every product.
Care
Follow the care label on the item. Try things on at home with the tags attached — shoes on carpet, since marked soles cannot be returned, and swimwear over your own underwear with the hygiene strip in place.
Size guide
Everything on this site is sold in UK sizes. Use the charts below to match your own measurements, and read the fit note on the product page — it tells you when a particular style runs large or small. If you are between two sizes, take the larger one. Returns and exchanges are free for 35 days, so it costs nothing to try two sizes.
Women’s clothing
Measure over your underwear, keeping the tape level and snug but not tight.

Shoes
Stand on paper, mark your heel and longest toe, and measure the gap. Measure late in the day, and use the larger foot.

| 12 | 29.6 | 11.7 | 30.6 |
| 13 | 30.5 | 12.0 | 31.5 |
Half sizes are offered on many styles and sit midway between the rows above — a UK 8.5 foot measures about 26.6 cm. Insole length is the inside of the shoe, roughly 1 cm longer than your foot, which is the toe room you want.
How to measure yourself
- Bust or chest — around the fullest part, under the arms, tape level at the back.
- Waist — around the narrowest part of your middle, usually just above the navel.
- Hips — around the fullest part, roughly 20 cm below the waist, feet together.
- Foot — heel to longest toe, standing, with the socks you would wear.
These charts are a general guide to UK sizing. Cut varies between styles — an oversized cardigan sits differently from a fitted jacket — so check the description and fit note on each product page.
