I went to ATL today and tried the white sleeveless button down top in a smaller size (fortunately they had one since it had been marked down to $14.99) -- and sure enough, it fit perfectly. It fit so well I bought a second one in deep coral. They'll show up in an outfits post soon. Thanks to your sharp eyes, I was rescued from an ill-fitting purchase once again!

But from now on, I will start with the smaller size and assume that's what I wear. I think it's just been a mental block. So hopefully I'll be a better judge of sizing. And I'll really believe you all when you say something is too big!
