Several questions coming up!

For starters, it's been several years since I've bought anything from Ann Taylor. How does sizing run? Also, are returns thru the mail easy with them?

What do you think of these shirts for me? Remember, I'm a rectangular hourglass. I think these are all good layering pieces right? What pieces (pants, cardi's etc.) would you suggest to match with these?
