Sometimes the most laborious part of the costuming process is the fitting of the pattern to the body. I (mistakenly) thought that buying the adult pattern & using size small would be appropriate for my 7th grade actor.
So now I am spending my time cutting up tissue & pinning it back together to properly fit the boy. I have to factor in that he'll be down on all fours throughout the play -- so it has to be roomy enough to "give" in the right spots. I also must make allowance for him wearing something lightweight underneath ('cause faux fur & stage lighting make for a mighty sweaty dog!)
