According to Pradas, the brand always gives her a direction and a look to guide the tans. This year it's all about a "sun-kissed radiance," like the kind most of us would have after a sunny vacation. "I always give my clients a full-body contour with the tanner and do at least two layers of the solution to achieve the right level of darkness," she explains. "I also take into account the models' natural skin tones and their routine. If they want to work out or shower immediately after they see me, I'll swap my Pro Sol Solution for the express version. That way they can rinse off the solution in an hour and the tan will develop over the next 24 hours."
