Kate Hudson channels the roaring 20s in red fringe flapper dress before changing into abs-baring orange as she swaps her formal threads for flirty fashion at MET Gala after-party.

She sizzled on the MET Gala red carpet in her striking Stella McCartney white gown earlier in the evening.

Now, Kate Hudson, 38, swapped her sensational designer threads for a show-stopping red fringe flapper inspired dress as she dashed for the after-party on Monday night in New York.

The Hollywood actress was dressed to impress in her 1920s look as she made her way to her waiting car in her head-turning blood red look, before changing outfits again just hours later.

Swapping her asymmetrical one-shoulder evening dress, Kate slipped into the flirty fringe ensemble which fell stylishly to her ankles, illustrating the ombré coloured detail to continue her night out on the tiles.

Her sleeveless tassled dress also featured a chic caplet draped over a single shoulder for dramatic effect, while the cocktail number swayed to the movements of her body.

Oozing style, the Almost Famous star complemented her head-turning party dress with gold metallic accessorise that gave her single toned look an extra dimension.

Adding inches to her petite frame, the daughter of Goldie Hawn slipped on pair of platform peep-toe platforms that matched her eye-catching clutch.

Although keeping her tresses in a sleek top knot, Kate added a vibrant red lip to her beauty look as she transitioned from the formal fashion ball to her night out with pals.

Showcasing her slender pins, the beauty teased at her bronzed legs as she graceful navigated her way into her waiting car while the look's fringe detailing draped over her. 

As she party-hopped throughout the night, Kate was later spotted in another bright and bold dress for a few hours at 1OAK.

The stunning star swapped her red for orange, baring her impressive abs in the tight, cut-out number.

With an a-symmetric neckline, the actress, who works incredibly hard on her fitness, showed off her toned and tanned shoulders.

The midi-length number clung to her sensational figure, while she kept things simple by wearing the same gold peep-toe heels.

Kate's red hot display comes after she wowed on the red carpet of the inaugural MET Gala earlier in the evening - which was chaired by Anna Wintour and co-chairs Katy Perry, Pharrell Williams and honorary chair Rei Kawakubo, womenwear's designer of Comme des Garcons.

Following the theme Comme des Garcons: Art Of The In-Between, she stunned in a white one-shouldered look from British designer Stella McCartney.

It is the first time the gala and exhibit has focused on one living designer since 1983, when it highlighted the work of Yves Saint Laurent. 

Costume Institute curator Andrew Bolton, told AP that Kawakubo is considered the world's 'most important and influential designer' of the moment and 'has consistently defined and re-defined the aesthetics of our time.'
