She has HOW many bikinis AnnaLynne McCord's bikini collection goes on and on… But can you guess which is from Walmart

When it comes to teeny-weeny bikinis, AnnaLynne McCord has an impressive collection.

From retro, high-waist pants to barely-there black halternecks and cutaway swimsuits, the 24-year-old has them all – and wears them on a regular basis.

Indeed, as muses, there are times when it seems she owns little else. Of course if we had the same ultra-toned figure and a beach on our doorstep, we'd spend most of our time in a bikini too.

Ever the party girl, AnnaLynne's favourite is eye-catching hot pink – ideally with flirty ruffles and frills for the ultimate in attention-grabbing beachwear.

The actress, who is one of the stars of 90210, has a high-end wardrobe for her role as the party-loving Naomi Clark, and is dressed in swimwear by Emilio Pucci and Calvin Klein.

But, when it comes to her off-duty days, it seems she prefers designs that have wider appeal.

A dazzling neon pink
monokini she wore to a pool party in 2009, was from none other than Walmart, and cost just $13. Clearly, when you're this genetically-blessed, you wear the swimsuit – it doesn't wear you.

Of course AnnaLynne is not completely lacking in A-list shopping habits. She shares favourite labels with a number of other stars.

The beachwear brand Vitamin A, loved by celebrities including Gwyneth Paltrow and Jessica Alba, is a particularly frequent choice.

And Gwen Stefani’s favourite brand, L’Space, also features heavily in the actress's swimwear collection.

But like every other beach-bound star, her wardrobe would not be complete without a number or two from Vix, beloved of everyone from from Kim Kardashian and Megan Fox to Denise Richards and Teri Hatcher.
