Kim Kardashian, 40, is back in her bikini. The KKW Beauty founder stunned in a the “Claudia” two piece by Nessy Swimwear as she hit the books for her weekly law studies. “Studying in the Sun,” Kim captioned her April 22 post, adding the sun, book and symbol of justice emojis. She kept her dark hair down in a loose beach wave, accessorizing with a printed headscarf, sunglasses and a pair of ex Kanye West‘s Yeezy foam slides.
