i used the jacket/coat from Simplicty 3997 Child Costumes to make the lab coat.
added 8" from the "jacket" part of the costume. used the front, back, collar and inside yoke for the coat and trimmed the sides of the jacket so it doesn't flair out like the costume.
when it's all pinned up
i figured i'd sell them on etsy...there are scrubs a plenty, but there aren't any lab coats. doctor, vet, mad scientist...possibilities are endless!
