I have ordered the Top in the S (usually wear size 38 or 40). The Innenbra fit super, that is, he had a Sützfunktion. However, the top lay under arm directly. What I personally do not said. At the same time also hit the top in the M in a tomato / blue sea. It was clear that the Innenbra not fit. But the armhole was still too tight. And the sport is now moving times and sweats also. The top would be in time wet in the arm. So both of them went back.
