Adriana Lima has spent the past few months promoting a new Victoria's Secret bra, and in each of her three in-store appearances, she has styled her hair differently. The first is a center part with loose waves, the second is the modern half up, half down, and the last is a side part with straight hair.
I know that Adriana is getting paid to show up and sign autographs, but she always looks so enthusiastic. (I would, too, if I had her paycheck!) Out of these three sleek hairstyles, which do you like the most on this super-happy supermodel?
