The mark of true visual beauty is whether it shines through without all the fancy window dressing. Meaning, a beautiful woman need not be dressed in lingerie or skimpy revealing outfits to be perceived as such.
Case in point, Victoria's Secret Angel Alessandra Ambrosio, who slips into some very casual outfits in a new photo spread, yet still somehow retains the characteristics that make her so pleasing to the eye. Perhaps it's because she does still reveal a bit. Just not that much.
Here, she's just an around the way girl. And we love her for it.
