FKA Twigs Wears NSFW Dress On Met Gala Red Carpet With Rumored Fiancé Robert Pattinson [PHOTOS]

FKA Twigs and rumored fiancé Robert Pattinson made their red carpet debut as a couple at the 2015 Met Gala, themed "China: Through the Looking Glass," Monday night in New York, and social media is all over it. But the buzz isn't about what a perfect match they are or their adorable display of PDA -- it's all about FKA Twigs' dress.

The 27-year-old British songstress took a big fashion risk, hitting the carpet alongside her man wearing a colorful, graphic — and NSFW — gown. The lace dress, designed by Christopher Kane, comprised shapes of multiple naked bodies splayed on top of one another in various positions. And right above the sexy, thigh-high slit: a full-frontal view of male genitalia.

With a dress that loud, it’s no wonder she went light on the accessories. The “Water Me” singer took on the high-fashion event with her hair in a high and tight bun. Her only jewelry for the evening? A flashy hoop through her septum piercing and an even flashier ring, rumored to be her engagement ring from Pattinson, on her left ring finger.

Although Twigs chose a very unconventional look, “Twilight” actor Pattinson went traditional. The 28-year-old clung tight to his might-be-fiancée’s hip in a fitted black tuxedo with a classic white button-down underneath.
