Polka dots evoke a carefree summer vibe. So it's no wonder they've been spotted on stars like Marisa Tomei, Cameron Diaz and Selena Gomez—only this time in the form of casual separates, not formal dresses.

Much like the sequined blazer, a polka dot piece—especially if it's colored—should be the only standout part of an outfit. Don't pair it with jeans that have rips and tears or accessorize with bright items like Cameron did. Otherwise, your polka-dot fun will have everyone wanting to poke fun! Follow Marisa and Selena's lead and keep the rest of your look simple. Check out the steals and splurges below to shop the trend.
