Converting centimetres to inches
Many size guides show both centimetres and inches, especially for US sizes. Here's how to convert easily:
1 inch = 2.54 cm. Divide your centimetre measurement by 2.54 to get inches.
Example: 74 cm / 2.54 = approx. 29.13 inches.

Model images as a guide
In most cases, we also show a model image along with information about the model's height and size. This gives you a better sense of how a given size looks and fits in real life.
Pay attention to the fabric
The fit may vary slightly between our different fabrics. Woven materials often feel more fitted, while jersey and knitwear tend to sit looser and more generously. Please keep this in mind when choosing your size.
Recommendations based on customer feedback
Our customers' feedback is invaluable to us, and we use it to continuously improve both our products and our service. That's why you may sometimes come across recommendations directly on product pages, such as "Runs large, we recommend sizing down" or "If you're between two sizes, we recommend choosing the smaller one". These recommendations are based on customer feedback — particularly from returns — and are intended as an extra tool to help you find the perfect fit.
