I think the collar is now wide enough. I need to knit two rows all around (meaning up the button bands and around the collar) and then bind off. I could get by with one additional skein - if that vendor would ever get back to me. I'm irked... it's been two days and no response. The next time I write about this issue, I'm going to tell you her shop name and recommend you never buy yarn from her.
I'm still hoping she'll come through. If she doesn't, I'll look at other options but I'd love to finish off my Sophisticate in the same yarn.
I also did a bit of knitting surgery last night. After finishing my BFF's cowl, I realized when I went to block it that I'd knitted one row incorrectly. See it? On the right side? I think she could have worn it and no one would have ever known the better, but my anal-retentive soul couldn't stand it. I cut off the offending section and reknitted. Now all is well. The new cowl is as long as the first version, btw; it's just not stretched out in this picture.
