The measurements are given in CM and all breeches and leggings are measured while laying flat. The length is the inseam length and the waist and hip are measured one way, so it is not the circumference.
The model on the images is 166 cm and uses x-small.
Our breeches are normal in size, but if you are in between two sizes, you should go up one size. The fabric is stretchy but with compression so they should fit really tight when you put them on. They should feel like a pair of jeans at first and then they shape to your body as you use them.
When choosing size, pick your normal size.
If you are still not sure about what size to pick or have any questions about the fit or the products, please send us an email at firstname.lastname@example.org and we will help you further!
