The communication with the seller is great and the delivery time is amazing! Normally I wear size S/36 and this legging is a little bit loose. However, I have tried legging size S before and that was a little bit too tight. So it depends on what fit you like. It also depends on the fabric; this one is quite stretchy. I definitely recommend it, also this seller!
top is great, leggings are transparent and big in waist.
