Need Help Desparately!

Hi all, been awhile since I posted anything, but I’m making an outfit for my granddaughter, and I am so totally lost. It’s called “Ruffled Edge Top and Pants” and it’s in Bernat Baby Jacquards “Play Day”.
I’m working on the front of the top. Here’s where I’m stuck!
[B]“Shape front neck: 1st Row[/B]: (RS) K16 (17-18-19). [B]Turn[/B]. Leave rem sts on a spare needle.
Dec 1 st at neck edge on next 2 rows, then every following alt row 3 times more. 11 (12-13-14) sts.
Cont even until armhole measuers 5 (5 1/2-5 1/2-6) ins ending with a purl row.

[B]Buttonhold band:[/B] Knit 2 rows. Next row: K3 (3-4-4), yfwd, K2tog, K2, yfwd, K2tog, K0 (1-1-2) sts. Knit 2 rows. Cast off knitwise (WS)
With RS of work facing, slip next 10 (12-12-14) sts onto st holder. Join yarn to rem sts and knit to end of row.
Rep from *** to *** as given above. Cast off[B]”[/B]
[B]I’m not sure what to do with the buttonhold band. Where do I knit this??? I have done the neck shaping. I’m just not sure how to do this part. If anyone can help me figure this out, I would be greatful. You can email me at [/B][B][/B]
Thanks in advance
