During the opening of the Fenty Hair line at Selfridges in London, Rihanna made beauty lovers gasp for air for her unconventional, glamorous fashion bathrobe.

While her outfit gives off the "fresh from the bath" feel, the superstar's classy hairstyle, nude makeup, and gold Amina Muaddi sandals up the high fashion game – the singer truly exudes pure elegance!

The bathrobe, also considered a fall coat is a version of the Caruso Coat with a whopping price of $2,230, according to PageSix. The look was enhanced by turning the lapels into an off-shoulder style and styling the tie belt.

For her hair, Rihanna opted for soft waves and to ensure that it will look natural and healthy, her hairstylist Ursula Stephen created the side-parted vintage hairstyle using Fenty Beauty's hair line products including Protective Type 5-in-1 Heat Protectant Styler.

This is a must-have before using heat on the hair to keep it hydrated, smooth, and without tangles and frizz. Set and style the hair's edges using The Controlling Type Hair-Thickening Edge Control Gel. 

In an interview with Vogue, Rihanna pointed out the importance of her hair when dressing up, treating it like her "crown."

For her makeup, Rihanna's makeup artist gave her a sultry look using shades that match her skin tone; warm neutral. For her face, she applied the Softlit Naturally Luminous Longwear Foundation in the shade 315.
