Thanks, Debbie and Renee! I called my local Loft and they hadn't even put them on the floor yet. I ended up buying the petite version in white. I think I really like it. I'll have to try it with a dress here at home and see how it looks in a non "skinny mirror." The sleeves are cropped and end at the bottom of the jacket--which I think is a weird length but looked fine rolled up once. I'll try to post pics later.
ETA: FWIW, I sized down. According to the size chart, I should be an 8P based on the chest measurement. The 6P had a closer fit through the body and still fit in the armscye and bicep. I think the stretch really helps. I'm in my gardening duds so no pics until tomorrow.
