Gwen Stefani is best UN-dressed at Vogue event as she flashes bra... and leaves Victoria Beckham and Jennifer Aniston in the shade

It's arguably one of the most prestigious fashion events held in Los Angeles.
So if there was ever a day to dress to impress, Thursday afternoon at the Chateau Marmont was it... as the great and good gathered there for the annual Vogue CFDA Fashion Fund Event. 

Show stopper: Gwen Stefani - here with Katy Perry - looked incredible in a tuxedo suit with just a bra peeking out underneath at the CDFA/Vogue Fashion Fund on Thursday

The best of the best: Gwen and Katy were the best dressed at this fashion conscious event

She's got the nod! Vogue supremo Anna Wintour approved of Stefani's show-stopping look, too

So it's ironic that the most stylish attendee actually undressed to impress; in a gorgeous tuxedo suit with just a see-through bra showing blatantly (and gloriously) underneath it.
Step forward the incomparable Gwen Stefani, 43, who wasn't the only star to wear a suit, but was definitely the one who owned it.
Keeping it simple, the blonde beauty styled her hair like Rita Hayworth, slicked her trademark red lipstick across that pout and added a chunky diamante choker.

Not VGood, VB: Victoria Beckham perhaps tried too hard with this outfit, as it didn't work as well as her usually beautiful creations

Talking fashion: Victoria chats to fellow fashion designer Laura Mulleavy at the party

Girl chat: January Jones, Fashion Fund finalist Jennifer Meyer (who just happens to be Tobey Maguire's wife) and Jennifer Aniston catch up on the patio at the Chateau Marmont

Starry, starry... afternoon: Aniston was sandwiched between Tobey Maguire and Isla Fisher as this Who's Who Hollywood event

The delightful Victoria Beckham, 38, was also there to preside over events; as she should be after becoming one of the most feted and effortlessly stylish designers on the planet.
Victoria, mother-to-four, looked lovely as always but had perhaps tried a little hard for the event in her head-to-toe cream ensemble.
Somehow the rigid mini-skirt didn't quite flow with the pretty blouse, one of the pencil numbers from her collection would've worked better.
