What is a tankini swimsuit, and why is it such a favorite of so many women? A tankini is an ingenious combination of a tank top and a bikini bottom. The result is super-comfortable, ultra-versatile swimwear separates ideal for mixing and matching. Some tankini tops are cut long to cover the midriff, which appeals to fans of more modest swimwear—yet these longer tops can also be pulled up to create a flattering ruching effect. Other tops are cut shorter to show more skin. Nordstrom offers tankini tops in traditional tank designs as well as classic halters, chic bandeaus and more. Tankini bottoms are offered in traditional low-cut bikini styles, 'cheeky' fits and high-waisted designs. You'll find loads of cute tankini separates to choose from at Nordstrom, including plenty of plus-size swimwear options.
