Pick up on smaller circular needles approx. 62-76 sts along right button band, then put 58 sts from right collar back on needles and pick up approx. 12 sts to center back = 132 -146 sts. Knit 2 rows seed st.
*** On the next row make 5 buttonholes evenly distributed along button bands - the bottom should be approx. 1 cm from bottom edge and the top should be just before the collar starts. 1 buttonhole = K 2 tog, yo. ***
***Knit 1 row seed st more (, then bind off sts around back of the neck and along the collar in seed st. ***
***Continue with 3 rows seed st along button bands – K 2 tog the 2 sts at the top of button bands every row so that there will be a smooth transition from neckband. After these 3 rows bind off the remaining sts in seed st.) ***
3 rows, then bo. (Total of 7 on lower portion.) Don't see any brackets in your post but there are couple parentheses. The K2 tog? Appears the decs are made where the buttonband meets the angle of the front neckline. At this point you're only working the lower portion...where the buttons/buttonholes are. That's my take. I could be wrong.
