Cowl sleeves

So, the latest Vogue Patterns catalog has this Guy Laroche, which, as far as I can tell from the flats, may have cowl sleeves. (I won't be absolutely certain until I have it, which probably won't be for a month or so — if anyone's got it already, correct me if I'm wrong.)

I don't see these often. Have a look at the Vintage Patterns wikia (if you block or don't mind all the ads) for a few; they seem restricted to the 30s and the 80s.

Like a neckline cowl, they can be made with or without pleats. Rhonda Buss drafts an example of the latter type here. Pattern pieces tend to look either squared off or forked at the top of the cap.

Far left: short pleated cowl sleeve on the blue dress; far right: both long sleeves are cowls, the green one having an opening, and the pinky-beige one pleats. (The brown sleeve on the upper left is not really a cowl; it just has a slightly droopy pleated cap.)

They're not the most classic, restrained look, which may explain why they don't show up often. I probably won't make the Laroche in its original form; I mostly want to experiment with it. It looks different from all of the above styles in that the pleats are nearly all in the underarm seam, not the cap, placing the fullness much further down the arm. So maybe it's a true cowl, or maybe it's just got some extra length being pleated up. The pattern piece will tell.
