I've actually tried on both the jackets you posted! (But I'm older, with a large bust.) On me, I didn't like the LOFT jacket. It felt too cropped, and the pockets on the front were not flattering on me. But if you have a smaller bust, that might not be a problem. As for the waist - I think we'd really have to see a picture of you in the LOFT jacket to see if it works for your body.
I really liked the Eddie Bauer jacket. I have an older model from them, and I much prefer this new slightly cropped one. It was a bit more feminine, didn't feel so boxy, and I liked the length a lot. But since I already have a denim jacket I felt I couldn't really justify buying another one that's essentially the same. Maybe I will if it goes on sale, though.
