As I mentioned on the blog posting, I have one of these mixed media tops from Loft and another one from Ann Taylor in the same basic design but with long sleeves. The woven front/stretch back is a brilliant design IMHO - stretchy in the back so room to move, and woven in the front for a more crisp appearance.
I just checked the Ann Taylor site and they have a bunch of them this year. Ann Taylor and Loft are owned by the same company and it looks like they've included this mixed media style in both brands.
Finds 1 & 2 are the ones I own, from about 2 years ago. Find #3 is one of the many offered on Ann Taylor's site right now; they have lots of sleeve lengths, colors, styles.
