There's an interesting elastic gimmick on both sides of the waist, which stretches about 2 cm each, for a total of 4 cm. See photos 5-7. Maximum waist size is about 41. Marked as XS, but I think it's equivalent to a Small. (However, it was too small for a 170cm-59kg male, and I gave up after wearing it once.) Has a loose center crease. Hemmed with iron-on tape.
