Millie Mackintosh bikini secret

We all know how much Millie Mackintosh loves to show off her amazing body, particularly in swimsuits. The Made in Chelsea starlet has been very active on social media lately, tweeting photos of herself in a variety of skimpy swimwear while she holidays with boyfriend Professor Green in Ibiza. There is no doubting her incredible figure, but now we know the reason behind why she always manages to look so flawless in her bikini shots.

Made-to-measure.

That's right ladies, Millie has been splurging on made-to-measure swimwear to ensure each bespoke bikini is made to fit her perfectly. But before you start pulling out the credit card, you must know that these one-of-a-kind pieces don't come cheap. The Quality Street heiress can spend over £450 on just one swimsuit which she designs herself in collaboration with Chelsea boutique, Biondi Couture. Located on the Kings Road it has been a regular haunt for many celebrity holidaymakers over recent years. Millie and her MIC co-stars, Binky and Cheska are regulars at the store, as is Kelly Brook. Even a few royals have been spotted buying up at Biondi Couture for their summer vacations.

"This is our busiest time of year and the Millie effect means that we are busier than ever creating swimwear for women wanting to stand out on the beach. Millie has an amazing body, we couldn't hope for a better ambassador for the brand," said Claudine Davies, owner of Biondi Couture.

"Millie has always worn our couture bikinis because she wants to make sure that she's wearing something a bit different from everybody else, and she is really involved in the design process."

As for the most elaborate swimsuit they have designed for a client, Claudine reveals that was a "£950 showpiece bikini for a woman competing in a fitness competition, it featured thousands of Swarovski crystals all sewn on by hand." Talk about bling-tastic!
