Can you help me figure out how to knit the sleeve for this dress?
Komok is my favorite forum, so I'm turning to the experts once again. It's a pity I saw this design so late; I would have knitted it for New Year's. Can anyone tell me if they've seen a pattern for this, or can you tell from the photo how the sleeve is constructed?

Комок - мой любимый форум, обращаюсь к мастерицам еще раз. Жаль, что увидела эту модель так поздно, связала бы к новому году. Подскажите, может кто видел описание или может по фото понять, как здесь вяжется рукав?






A very interesting dress! The sleeve here is a raglan; I know from experience that making one like this isn't very easy, but such items fit flawlessly. Regarding the knitting method, I agree with Tatyana. Start like a regular sleeve with the required number of stitches for the ribbing, then you need to calculate the increases so the armhole is the right width. If you are using medium-thickness yarn, you need to make increases every 6-8 rows on both sides. Calculate in advance how high the windows will be, whether they will be wider or narrower, and how many rows that will take.
Further, you can do it as Tatyana suggests: bind off the middle stitches and finish both halves separately, taking the increases into account, then knit the strips in garter stitch and sew them into the required sections. But this must be done very carefully so that the flat seams are invisible. Or you can do it differently: after knitting part of the sleeve, cast on the required number of stitches onto the needle, knit the crossbar, then bind off again, and do this several times.
Then you sew the sleeve to the dress and knit the neckline ribbing as one piece. Good luck with your project, please share the result later)))
