Ready for bed? Braless Rihanna risks a wardrobe malfunction as she sports JUST a feather-trimmed night shirt with two belts at Met Gala after-party.

She was sporting one of the kookiest looks of the evening. 

And Rihanna continued her roll of out-there ensembles as she arrived at the Met Gala after-party on Monday in a nightwear-inspired getup, just hours after sweeping the steps of the Metropolitan Museum of Art at the heart on New York's 5th Avenue.

The 29-year-old Rude Boy hitmaker looked nothing short of sensational as she wore just a bed shirt with a duo of belts having transformed from her outrageous floral gown, which ground the red carpet to a halt hours before. 

Rihanna is known for both her sexy ensembles and wildly kooky looks, meaning the outlandish nature of the annual Met Gala is the perfect outlet for her funky ways. 

Hitting the red carpet, she rocked a gown from the Comme Des Garcons 2016 Fall ready-to-wear collection that resembled flowers blooming all over her body - with the label being the theme of this year's show.

Later on however she changed into a wholly different yet equally crazy look by slipping into a slinky white bed shirt which she cinched in at her tiny waist with the addition of two bold green belts. 

The green accessories coordinated with her backless, boudoir-inspired mules complete with a teal length of marabou fluff as a trim.

Matching up with her fluffy shoes was the trim on the wrists of her ensemble which were huge and plush while matching her dusky pink pouch handbag. 

She kept her hair in the same style as she sported on the red carpet, with a staggering bun sitting just behind a thick full fringe. 

Despite the after-party being in the dark of night, Rihanna suffered for her style as she peeled on a pair of huge square pink sunglasses.  

The theme of this year's Met Gala was Rei Kawakubo/Comme des Garçons, with the focus being on the avant-garde designer's technique with silhouettes, draping and fit.
