I usually use size xl and ordered size xl, however, the product did not match the size. So you should take one or two sizes bigger

Thank you very much for your feedback! The high-waisted lower parts of the Koucla do have a smaller waist than normal, so we recommend a skirt for those with a narrow waist. The pelvic girth should correspond to a normal size. :) <br />

You can exchange the skirt for free with any other product in our range. If you need help choosing the right product or size, our customer service will be happy to help! The skirt also has a normal 14 day return policy. :) <br />

Have a nice weekend!
I bought it after a pregnancy divorce. I usually use the size xs-s and from this I chose the size m based on that instruction table. I would have liked the corset to be a little tighter with those tightening stuff.
