Halloween costumes with glasses

If you still haven’t decided on a costume for Halloween this year, consider this: You can use a single focal-point accessory, like glasses or sunglasses, to quickly and easily emulate your favorite celebrity or fictional character.

Here are some of the most recognizable, bespectacled looks you can dress for:

Not-so-risky business

Even if you haven’t seen the classic 1980s film “Risky Business,” you’re probably familiar with its most iconic scene. Who can forget Tom Cruise sliding through his living room in little more than Wayfarer sunglasses, a white button-down shirt and underwear — all to the strains of Bob Seger’s “Old Time Rock & Roll”?

If you love the shades but prefer pants and R&B, consider a Blues Brothers costume. You’ll need a boxy black suit, skinny black tie, black fedora and a button-down white shirt to go with your Wayfarers.

Technically, you could do both costumes at the same time.

Big personality, big glasses

If you love throwback inspiration, you might want to add a bit of nostalgia to your non-costume. Round black frames are the hallmark of eccentric fashion icon Iris Apfel and the late comedian George Burns.

Don the frames and grab a fake cigar to go as Burns, or, if you’re more of a fashionista, go for an even heftier pair of glasses to embrace Apfel’s motto: “More is more.” Add big colorful necklaces and bracelets, and anything else you like to complete the Apfel look.

Easier-to-recognize characters with big round black frames include Waldo from the “Where’s Waldo” books — just grab a red-and-white-striped shirt and hat — and Edna Mode from “The Incredibles” — all you need for Edna is a plain black dress, black tights and a red scarf.
