Thanks! I thought that the top/arms ran a little large and the bottom part of the dress ran a little small, but maybe that's what you would expect from a sweater dress? Anyway, I went with the larger of the two sizes I usually take--the bottom of the dress is not very forgiving, so even with the extra room up top, I'm not inclined to try the smaller size. Probably depends on your body type, though. I'm 5'8" and the dress hits a few inches above my knee.
