According to this size chart www.etoolsage.com/converter/plusSize.asp you are wearing european 54/56. There is possibility that you may be able to buy clothing in clothing like C&A. As far as I remember there is one on Alexander Platz. If not there is Ulla Poepken or something like this (keep in mind I'm a guy ) just of the Alexander Platz - they keep bigger size though are quite expensive. Anyway I've been to Berlin several times but I don't live there - if anyone can verify my info I'd be very pleased
