In Russian s (75/80 V)-fig knows, pulls everything, but you can walk and even train. And m probably would sit better, but slipped with active activity.
The quality is just beautiful and the size corresponds to the European size so take there is usual size. I love it. I'll post a picture later. The seller is very nice and answered all my questions about the size.
Took S, reading reviews. My size on the top of M, here I usually take L, chest 80, under the breast 75. SKA is too small. She climbed, but the fat is heated between the ribbons. If the lower elastic band is slightly stretched in the sock, then there will be norms. I hope that it will be so, as I liked the top, tight, looks good. But with the parameters 75 V is better still m.
