If anyone knows about finding the perfect swimsuit, it’s got to be Kim Kardashian. But the reality star admits that bikini shopping is a challenge even for her — especially since she’ll only wear tie-bottoms. To make swimsuit season a little less stressful for her fans, Kim has posted her foolproof bikini guide on the official Kim Kardashian site. Among her top tips is making sure to get the correct size suit — rather than trying to squeeze into one that’s too small. And she loves the flattering cut of Ed Hardy’s new swimsuit line and bikinis by Sassi, just like the purple ruffled one she’s wearing here. Besides just getting the perfect suit, Kim recommends wearing big sunglasses, flip flops, a sarong and — of course — sunscreen! Check out all Kim’s bikini tips at officialkimkardashian.com.
