Kristin Cavallari In Seashell Bikini Wears Her 'Pearls At The Beach'

Kristin Cavallari has been mixing business with pleasure as she stuns on beach sands to promote her Uncommon James brand. The reality star, 37, posted to her Instagram last week all sunkissed and in a stylish swimsuit look, speaking of "pearls" in her caption as she plugged her best-selling jewelry brand. Updating her account as she continues to make headlines for dating 24-year-old boyfriend Mark Estes, Kristin stunned in a strapless-style bikini with neckties, showing off her sensational figure and looking gorgeous as ever. Fans have left the podcast host over 33,000 likes.

Scroll for the snap. Standing amid a blurred backdrop of rocks and ocean waters, Kristin sizzled in a cream bikini top with a seashell finish. Keeping classy in her slightly ruched swimwear, the Laguna Beach alum flashed her rock-hard abs and hints of her cleavage, also drawing the eye to her svelte waistline as she modeled a low-slung sarong skirt adding pops of brown.

With those thin neck straps and a bust accent accentuating her curves, Kristin wowed as she sported beachy-waved blonde locks, going heavy on the bronzer and rocking a frosted lip. Adding in bangles, arm bracelets, plus layered necklaces that included one with a pearl gemstone, Kristin matched her caption to her photo, writing: "Why not wear your pearls at the beach." She posted jointly with Uncommon James.

Anyone swiping got more snaps from the shoot, including a leggy display at the end, where Kristin Cavallari revealed her skirt to be a thigh-skimming mini one. "She gets prettier by the minute!" one fan replied.

Also promoting Uncommon James was this party-themed post. Looking incredible in a sparkly, strappy dress worn braless last fall, Kristin got festive just one month before Christmas, showing off her glittery look in party mode. "All the party girl feels for the new MIDNIGHT collection @uncommonjames," she wrote.

Noting that Uncommon James items don't cost the earth, Kristin told Elle: "I just don’t think you have to spend a lot of money in order to have great style or to look and feel great, and that’s just as simple as it is," adding: "I think fashion should be affordable for everybody." Kristin is also founder of her Uncommon Beauty brand, plus Little James clothing.

Fans went wild for this selfie as Kristin posted a selfie from her spacious, shoe-filled closet in April. Going itty-bitty in an off-white bikini that showed plenty of skin, the mom of three flaunted her toned legs and abs, also reminding her followers of her curves. Over 100,000 likes have been left. Kristin Cavallari has a reported net worth of $30 million.
