Took me a bit to figure out how to read the designer’s chart. What I did:

CO 24
K 3 rows
K5, PM, K3, PM, K8, PM, K3, PM, K5
K across doing a Kfb before & after each marker
K next row
Repeat these 2 rows until 72 stitches, ending after the K across row.
I worked the button holes on rounds: 6, 10, 14
Divide body/sleeves: K11, place 15 on holder, K20, place 15 on holder, K11
stitches in the holder are for sleeves.
Knit 1 row with all live stitches on the needles (body).
Knit lace pattern for 5 repeats.
K 3 rows
BO

Sleeves:
Knit in the round.
Put stitches from 1 holder on needles
Join yarn & knit around making sure to other 2 stitches under the arm together (14 stitches)
Work lace pattern 3 times
3 rows of garter stitch
BO

Finished with 3 tiny 1/4” rhinestone buttons.
