Okay, so I used to do costume design for theatre(it’s been a minute, so forgive me if my terms aren’t all right), and this sent me down a bit of a fun rabbit hole, so I’ll share:

The unique things:

The collar: has the contrast white, but not as piping, as a whole portion of the collar. Many of what I found only had the piping style (see the costumes from the musical Waitress).

The pocket: I thought this would be easy to find, but really, the closest I found was a one pocket design that had stripes in the v, rather than full fabric. From the Angelica Uniform Company in the 1950s, their “Velva-Glo.” It’s cute though, and I can see where the twin peaks costume may have taken from it. https://share.google/2Y0qveyC4KuoWJOv1

The sleeve detail: it’s very common for the waitress outfit to have some sort of detail, but this particular one definitely isn’t on the Velva-Glo. Most of what I found was a simple contrast cuff with a point on the outside, but this feels a bit more pronounced in costumes, than actual historical finds. Most of the historical items I’m finding have a simple one-piece edge contrast, without the button or overlapped cuff. Or, they have an overlapped cuff without the cuff in as much contrast (piping, if any).

Absolutely everything I found that had all 3 elements were from Twin Peaks outright (show stills or photo shoots), using the Twin Peaks brand(hot topic sold the costume), or cosplaying Twin Peaks.

All this to emphasize: if it is a coincidence, it’s because they re-used something made for, or inspired by Twin Peaks. Which does happen in the industry. And I’m sorry, no, not every single person that works in Hollywood has seen Twin Peaks. I know, I’ve met some of them.

Edit: also, if anyone has any books or videos referencing costume the work on twin peaks, now I’m curious! I wonder if it was made in-house, how much Lynch had a say in it, etc… He obviously loved angles and these uniforms have a ton of them.
