I don't always have the most cooperative knitwear model but she was thrilled to do a photo shoot for this one.
I can't speak to the other sizes but the sleeve caps and armscyes still seem too big to me on the 4T size. Perhaps it was a gauge issue - I might have knit more loosely on the short row sleeve caps than elsewhere. But if I were to knit this again (and I very we'll might), I'd make the armsceye smaller and reduce the number of sleeve stitches at the upper arm accordingly.
Otherwise, this was a great pattern. The lace was simple but just enough to keep things interesting. I always like short row sleeve caps. And there was minimal finishing (especially because I worked the neck and button bands at the same time, rather than doing the neck band first as the pattern suggested).
I'm calling this one a winner!
