This sweater is more suitable for the winter because the inside is wonderfully soft roughened. An absolute Kuschelpulli.
But here you have to say quite clearly, M or 38 (both is specified here) is very very small. I usually wear 38 in shells, and have usually also some slack in it. This hoodie here is not elastic and is like a sausage skin on the arms, chest (B-Cup, so nothing exceptional) and body to. If you like this, which is the size it right .. I would order me to feel rather 1-2 size larger, because this is restrictive and in no way be seen as in the picture. If you normally wears a size 3, it should then be just right, about as seen in the picture.
That you should definitely consider when ordering, otherwise as I said, a wonderful sweater, which is really recommended !!
