Sea Change: Swim retailer Everything But Water is making two big moves this summer: First, it's supporting the 5 Gyres Institute, a California nonprofit dedicated to ending plastic pollution in oceans, by donating 25 percent of sales from an exclusive swimwear capsule collection (four styles) from Vitamin A. The retailer is also putting its 30-plus years of experience to work with its very first swim line. In addition to the superior fit, all the fabric has four-way stretch and is rated UPF 50+ for sun protection.
