That’s right. You heard me: POCKETS.
There have been so many bad takes out there on the history of pockets in the past couple of years. What they have in common is that they’re written by people who aren’t costume historians. Because I am here to tell you, pockets were a thing for women in our era of focus. They didn’t magically disappear and turn into to “reticules” as many people maintain (this was gospel once upon a time, but has been thoroughly disbunked).
When you look at period gowns (especially morning gowns and day dresses), you see “pocket holes” on a lot of them. These are invisible in most of the pictures you see on museum sites though, and their existence is often not noted in the description. But if you look at books like COSTUME IN DETAIL by Nancy Bradfield, you’ll quickly see that there are pocket holes all over the place.
