I'm postnatal leave and I did not enter my usual 34. I thought that the SM size should be good, as it usually corresponds to the 36-38. Upon receipt of the legging, it seemed very very small, rather equivalent visibly a XXS 32. Fitting: Indeed, it's very tight and a bit difficult to put on. it reminds me stockings prescribed at the end of pregnancy! Except that it is cheaper. Immediately, it was so tight that inevitably, it refines the silhouette! Also, the legging feels good: it is because it contains a product Nivea (Q10 - I do not know what it is) basically it smells nivea cream, which is not unpleasant. And the statement is: MOVE! There's that how you firm up!
