This Legging tried for seven days is entirely satisfactory. Size S - M is well suited to those who wear a size of up to 40 (see below measurements). Its elastic material adapts to the body and sleeve without compressing lesjambes and without bringing discomfort in movements, c is very flexible and it's put on easily. The ultra-flat seams are invisible, my wife said "it is really too well legging, c is the best of the best, I buy it back in." The firming effect is obvious over a period of 7 days, thigh circumference 48cm has not changed but the belly circumference increased from 89 to 87 cm.
