I love the jeans! (Have they disappeared from the Nordstrom's site now?) The jeans are amazing on you!
I am always torn between two sizes and can never figure out how things are "supposed" to fit. I thought the smaller sizes gave you great shape, but if you weren't comfortable, I think, as Sarah says, these look fine. I think the white shirt seemed to lay better in the smaller size - this one looks a bit more bunchy at the bottom maybe? But it doesn't look bad. (As I said, please don't listen to me because I never know how things are supposed to look!)
I think this whole outfit is fabulous! It looks so modern without looking "trendy." Very stylish! How do you you feel in it?
