Buttons!
Buttons, straps, and strings.
They used buttons.
Before the zipper was invented in 1913 to close clothing required laces or buttons. When it was first invented it was called clasp locker and originally it was only used on boots and tobacco pouches. It took 20 years to convince the fashion industry to use it. In the 1930's a sales campaign began for children's clothing with zippers and in 1937 French fashion used the zipper instead of buttons on men's trousers. The next big thing in zippers was when zippers could open both ends like on jackets.
