DayVies: Thanks for the 411 on Gap policies. I remember that the next time I wish to return.
KaryMK and Susie: Pancake chest refers to the subtle squish your bosom get when buttoning or zipping a slightly too small jacket. It creates a bit of a "pigeon breast." Fortunately, this jacket stretched a bit, and it looks OK zipped now. I didn't expect that. Of course, I'll not wear it zippped often, anyway.
Una: This is amazing comfortable, actually. It's lined in cotton in the torso, and rayon acetate in the sleeves. I don't like confining items, so I tend to prefer knit jackets to woven, but I'm happy with the way this feels during the day. I was lucky enough to get it for 40% off, too.
