When you're just not sure what to dress up as for Halloween [1], you can always rely on a popular classic: Holly Golightly from Breakfast at Tiffany's. You probably already have everything you need in your closet and makeup kit. Plus, this is one costume that is 100 percent work appropriate. Follow the simple steps below, and you'll be channeling this eccentric-yet-misguided society girl in no time.

• For the makeup: It's all about creating a peaches-and-cream glow with creamy, warm pink cheeks and lips. Pair with black eyeliner and curl-enhancing mascara, along with a touch of champagne (what else?) shadow on the lids. Finish with well-groomed brows and false lashes as needed.
• For the hair: If a tiara is hard to come by (or a tad pricey for your Halloween costume budget), go with an oversized rhinestone barrette instead. Of course, your look won't be complete without your hair styled in a French twist and baby bangs — cheat the style with this Holly Golightly wig [1] ($35).
• For your ensemble: Don a slinky black halter gown, long formal gloves, rhinestone earrings, and a multiple-strand faux pearl necklace, and you have yourself an iconic getup if there ever was one.
