Back/shoulder ease – organist/conductor
I am constructing an 18th century gentleman’s suit for an organist / harpsichordist / conductor to wear while performing and conducting Baroque concerts. I am using Butterick pattern B3896 for the coat. My client is concerned that the muslin back is too tight for him to reach the organ keys comfortably, and when he lifts his arms to conduct the coat rides way up.
Does anyone know techniques to give enough ease to let him play and conduct comfortably, while leaving the back appearing to be flat and smooth when his arms are down? The back of an organist/conductor needs to be at least as attractive as the front!
Any suggestions would be greatly appreciated!
