When it comes to Halloween costumes you can wear to work, a sexy anything is inappropriate, and black cats, bumble bees and witches are blasé choices. This Halloween, impress your coworkers and dress up as a classy historical or fictional lady. Pull from your existing wardrobe to make these strong and stylish women come to life.

Peggy Carter

Captain America’s Peggy Carter is so kick-ass, she’s the star of her own show. Agent Carter is best recognized in two distinct outfits. For her wartime look, wear a brown skirt suit, white blouse and black necktie. Add air force emblems to the jacket. For daytime Peggy, don a red fedora and blue skirt suit with a wide-collar, white blouse. Wear t-strap heels to top off the look.

Jackie Kennedy

Who epitomizes class and style better than Jackie O? For classic Mrs. Kennedy, wear a pink, tweed suit jacket and skirt with a wide-collar black blouse and matching pillbox hat. Accessorize with white gloves, pearl jewelry and ballet flats or sensible heels. In lieu of pink, any pastel color will do.

Holly Golightly

You probably have a little black dress in your closet, so why not dress up as the lady who made the LBD famous? In “Breakfast at Tiffanys,” Holly Golightly wears a sleeveless, floor-length black dress, accessorized with a chunky pearl and diamond necklace, and a petite, diamond tiara. Complete the look with elbow-length, black gloves and a long cigarette holder.

Scully and Benson

If your closet and budget are more limited, consider a lady of the law. Clip on a DIY FBI badge to the jacket of a black or navy skirt suit and presto! You’re Agent Dana Scully of “X Files.” If pants are more your style, become Detective Olivia Benson of “Law and Order: SVU.” Rock pin-striped slacks, a blouse and blazer with boots. Or, wear black jeans, a solid-color top and a lightweight leather jacket. Don’t forget the NYPD shield around your neck or on your belt.
