Finding a flattering swimsuit that looks expensive and earns compliments usually means spending way more than you want to. That's why I was shocked when the Herseas ruffle bikini set delivered the same elevated look as some designer styles I was eyeing. I originally fell in love with a chic navy set from Marie Oliver, which rings in at nearly $275 for the full look. It's polished, tailored and undeniably gorgeous, but not exactly an impulse buy.
