Let’s try a simple style brainteaser. You’re packing for an eight-day vacation that’ll take you through three cities with different climates, with temperatures ranging from 50 to 85 degrees Fahrenheit. You’re also flying a discount airline that allows you no more that 40 pounds of luggage. Fifteen of those pounds are, um, reserved for shoes.

So, how many pounds of scarves do you bring? For full credit, write in ounces.

Scarves, of the silk, lightweight variety, are an easyJet traveler’s BFF. They lay flat, weigh nothing and can be worn on any part of your body (neck, head, wrist) and change a monochromatic look instantly. While silk squares once shielded Grandma’s bouffant, scarves are now a youthful way to add color or prints without adding weight to your frame — or your roll-on.

I wear a scarf almost every day. Sometimes, I tie one around my neck. Often, one will peek out of a pocket or swag the handle of my purse. Last week, I wrapped one around my wrist to mask a particularly ugly ironing burn.

Once “Pan Am” takes off, (pun intended), 1960s stewardess scarves will be everywhere. I recommend jetting to Goodwill for some vintage ones, now. A few dollars can go a long way in preventing overweight luggage fees.
