This Swimsuit Is Expensive, but I Can Tell You It's Worth It

As a fashion editor, I get asked time and again what items are actually worth spending money on. Über-stylist and Rosie Huntington-Whiteley's main lady, Cher Coulter, once told me that high up on her list of recommendations is a small Saint Laurent day-to-night bag, a decent pair of loafers, a forever trench and a Victoriana blouse. Some women always invest in winter coats, others in occasion dresses or designer denim, but me? I'm a (relatively new) advocate of expensive swimwear.

It all started when my stylist friend and swimwear addict Lily Russo set up an online beachwear website with her sister and mother in 2012, called BeachFlamingo.com. Since then, the resortwear market has been expanding—one recent report predicts that the global market for swim- and holidaywear is set to exceed $20 billion by 2019. Added to that, any high-fashion buyer will tell you that they're ploughing more spend into the luxury side of this booming department. There are a high demand and an increasingly varied supply, but one designer swimwear name will always be referenced, no matter how many new labels come to the fore: Karla Colletto.
