Kim wore a midnight blue gown by designer Lavin to the event in New York and the dress' saucy thigh-high split meant she could display her right pin - in the style of Angelina Jolie!
The US star's look was a far cry from last year's outfit choice, which saw a heavily pregnant Kim being compared to a floral carpet. Oops!
Kim was joined by Kanye at the showbiz event and, despite rumours that they tied-the-knot over the weekend in a low-key courthouse ceremony, there was no sign of a wedding ring on either of their fingers.
Clinching in her waist with a thick belt, Kim's dress showed off her curvaceous figure and she teamed it with a pair of high black sandals.
Along with Kanye, Kim was also joined at the Met Ball by sister Kendall, who stunned in a Topshop gown.
Kim has since shared an array of black and white photographs taken on the night, including one of herself with supermodels Naomi Campbell and Cara Delevingne and actress Kate Bosworth.
The mum-of-one also Instagrammed a snap of herself taken moments before she and Kanye walked the red carpet. Alongside it, she commented: "#FirstLook #FinalTouches #Lanvin #AlberElbaz #LorraineShwartz #MetBall."
