I actually prefer Blair Waldorf to Leighton Meester, if that makes sense. When dressed as Blair she looks so much prettier than when as herself. Blair has the cutest capes, hairbands/bows, and shoes. Leighton herself dresses in a more overtly sexualised manner that doesn't really appeal to me. For instance, those GQ pics (and many of the red carpet pics) upthread, are nowhere near as attractive to me as her as Blair eg. the pic just above with the cape, hairband, patterned tights and cute heels. Blair almost always dresses exactly how I like women to look.
