Isabel De Nyse Conover, A Complete Course in Dressmaking (1922)
“ Here, line the end of the facing which projects beyond the waist. Gather the lower edge of the waist. The easiest way of finishing the waistline is with a casing and elastic. This does away with the troublesome finish of a grosgrain belt and placket closing. Draw up the gather threads in the waist and lining just a little, throwing fullness at the sides of the fronts and back. The waistline must be kept sufficiently large so that the waist will go over the head when the closing is lapped and pinned at the bottom. ”
