JJXX Size Guide
JJXX is the womenswear label from Bestseller, the Danish group behind Jack & Jones, built around relaxed denim, knitwear and everyday separates. Garments are labelled in EU sizes, so a UK shopper subtracts twenty-eight from the EU number and a US shopper subtracts a further four: EU 38 is a UK 10 and a US 6. The brand publishes body measurements rather than garment measurements, so compare your own measurements against the charts below rather than sizing by the label.

Sizing Tips
- Measure the widest part of the chest with the tape horizontal all the way round.
- Measure the waist at the natural waistline, not at the hip of your jeans.
- Measure the hips at the widest point, roughly twenty centimetres below the waist.
- Denim is labelled by the numeric waist size, so use the bottoms chart rather than the alpha size.
- The L size covers EU 40 and EU 42, so check the product page when you sit between the two.
- Oversized and boxy styles are cut deliberately loose; take your normal size unless you want extra volume.
