Rae, I forgot all about the flu when I saw your fresh face sporting "le no-makeup" look. I wish I looked that good when I was sick and sleep deprived!
Anyway, I hope I didn't talk you into the wrong size. I think it will stretch a little, without ever "stretching out". It looks really good on you, and it has just enough extra length to keep you covered. If you wear a lot of oversized things, it can be nice to have a body-con piece or two. Plus you will probably wear it under blazers and such, no? If not, you can always exchange it for a small.
You look great in it, and I hope your family turns the corner soon and you get some rest.
