Kim Kardashian at 2013 met gala

Flower Power

1/22

Now a stalwart on Met Gala red carpets, Kim made her debut at fashion's finest night in 2013, when she was heavily pregnant with her first child, daughter North. For the evening, themed "Punk: Chaos to Couture," the Keeping Up With the Kardashians star made an unforgettable appearance in a skintight floral dress designed by Riccardo Tisci that put her baby bump fully on display. Two years later, she took the meme-worthy outfit out of storage to dress up as herself for Halloween while pregnant with son Saint.
