Size S fits OG85/OT73/OB93 (I wear bottom M/top S/75b), waist about 50, and tightened the adjustment to the maximum in many places, the straps to the neck are removable (one was a bit longer) and without them, I liked it better, with them there is a tightening effect :)) Arrived very quickly from the parcel locker, the only downside is the front seam of the panties is not very well made, but who would even notice that) The set is great, you order and say knee-to-knee.
