Rachel Zoe keeps her bikini body under wraps in a black sarong on family holiday

Despite spending Christmas Eve on the beach in St Barts, Rachel Zoe is keeping her tiny figure under wraps.

The 41-year-old stylist to the stars spent the day soaking up the sun in the French territory with her family.

While husband Rodger Berman peeled off his shirt, exposing his bare chest, Rachel remained covered up the entire time.
