Lo is quite often accompanied by Lauren also in the pics which is normal considered how good friends they are. Maybe that's why I don't see her so much as an individual stylish girl. More to me Lo is very cute, a bit funny actually but not in a bimbo kind of way. You know the persons that are just a little light hearted, I find it adoring. She doesn't seem to think too much which is quite special in Hollywood where everybody are all about themselfs, stressing about their looks and what the others think of them. Of course appeareness is important and surely she cares about it but in the right easy breezy way. Her natural make-up and hairstyle complete well her look that often means a nice dress with heels without too many accessories.
