Hailey Baldwin reveals a designer thong in a daring backless dress at the Met Gala.

Hailey Baldwin was looking pretty in pink at the 2019 Met Gala.

The model, 22, worked her magic in a solid cotton candy pink Alexander Wang dress while celebrating fashion’s biggest night in New York City on Monday.

Though the look was not commanding as much attention as the other flashier looks at this year’s Camp theme event, Hailey’s simplicity made her stand out at the bash.

The shimmering turtleneck dress left little to the imagination, even though it covered up just about all of her physique.

Hailey’s dress clung to her fabulous figure, and it’s backless feature put some serious amounts of skin on show.

Not only that, but the dress appeared to flash a pink thong decked out with a glittering ‘Wang’ button.

Adding a youthful touch was the velvet bow scrunchy used to hold up Hailey’s high ponytail.

The Met Gala is the annual fundraiser for the Metropolitan Museum of Art’s Costume Institute and is the most glittery and exclusive event on the New York fashion calendar.

It is famous for attracting luminaries of Hollywood, of fashion, music, sports, TV and the stage for an evening of fashion and charity to mark the museum’s spring exhibit.

This year, the exhibit and gala are dedicated to the idea of ‘camp,’ as defined by Susan Sontag’s 1964 essay Notes on ‘Camp.’

The Met Gala, formally known as the Costume Institute Benefit, is always chaired by a team of high-wattage celebrities, and this year is no exception.

The event is chaired by pop star and actress-of-the-moment Lady Gaga, tennis star Serena Williams, and singer Harry Styles, along with Gucci designer Alessandro Michele and, as always, Vogue editor Anna Wintour.

Wintour said she believes this year’s Met Gala to be about ‘self expression’ and ‘individuality’, noting that she wanted to see ‘outrageous, fun, tongue in cheek’ fashion on the red carpet.
