I can connect in terms of size the Vorrezendenten. The undershirt falls 1-2 sizes smaller than indicated. Normal size XL fits me most, in this case the shirt falls but more like ML. In it I look like a sausage in their jackets. If the size of data to be adjusted can be by my side for the price but nothing else complain. For quality, I can not have make since I can not wear the shirt. Return comes at the price for me not in question, because the effort is worth hardly. I will now give to one of the slimmer friends.
