Dear Coco Rocha, The problem with your fabulous new Gap ad is this: We look at your perfectly bare face, your casually creased sleeves, the effortless pop of the waist in those jeans. We see the tangled hair and the easy smile. And then we think, "Oh, that's so easy, it'll take five minutes to get dressed like that!" But of course, no. Only you can get dressed like that. For the rest of you trying to pull off this look, we suggest a sorta-Kate-Moss shrunken vest or cropped bomber on top of the shirt to help define the shape of your torso, and maybe a tinted lip balm. As for the jeans, well okay, those really do look perfect.
