Crystal Hefner's Bikini Collection Is Quite Extensive (PHOTOS)

This week, Crystal Hefner fans got an eyeful of the buxom Playboy model when she posted a ton of Instagram pics of herself modeling skimpy bikinis.

It all started with a red bikini top with crystal (get it?) embellishments that revealed an eyeful of cleavage. Then the 28-year-old took a break from the two-piece and changed into a nautical-inspired one-piece. Finally, on Thursday, Hugh Hefner's wife sported a sexy white bikini with beading underneath a matching vest and paired with a silver and pearl necklace.

Naturally, the DJ is used to posing in bikinis and as a result, her collection is quite extensive. For July 4th, the model sported a patriotic stars and stripes two-piece. Crystal also loves posing in the Playboy Mansion's massive closet wearing (what else?) her many, many bikinis.

So we decided to take at look at Crystal Hefner née Harris' bikini collection. Take a look below:
