1. Sweatpants. Can we all just come to one general conclusion on this one? Friends don't let friends travel in sweatpants. Time after time, I see people in gray heather sweatpants with their last name on the bum, and it makes me just want to give them an anonymous note saying, "I'm glad you're comfortable, but you look like a slob."
2. A strong fragrance. Now I love a good scent but traveling is NOT the time to be experimenting with cologne or perfume. Be respectful of the other passengers on board—they might have scent allergies or maybe are not a fan of your new favorite scent du jour. This rule also applies to bringing food on the plane. Perhaps you think twice before buying super smelly food from the food court for onboard consumption. That would be really nice.
3. Provocative clothing. Dear Lord did I experience this while traveling this past weekend. Women wearing low cut shirts or shorts that barely covered their posteriors. If a parent wants to cover their children's eyes because of the outfit you're wearing, take note. And if you're unsure of what to wear, just ask yourself, "What would Jackie do?"
4. Complicated shoes. I'm guilty of this. I'm really short, and I used to wear platforms when I traveled, but boy have I learned. The more complicated a shoe is to take off, the longer the passengers behind you have to wait in security. Also, airports are large places that sometimes require a lot of walking and/or running to gates. Skip the stilettos and reach for a comfortable pair of loafers or fashion-forward sneakers. There are so many elegant options out there right now.
5. Loud and expensive jewelry. It will set off the metal detectors. It will draw attention to you. If you MUST, just be careful.
6. Pajamas. Pajamas are appropriate to wear when going to bed. In the comfort of your home. That is the ONLY place.
7. Oversized coat. This is going to take up a lot of room either in your seat or in the overhead storage compartment. Pick a more considerate option.
8. Shorts. Airports and airplanes are dirty. They are also usually really cold. Why subject your legs to that? Put on your pants!
9. Flip flops. They're not sturdy traveling shoes, and like I said above airports are GROSS. If you must wear sandals choose a secure pair.
10. Fanny packs. I know they come in and out of fashion. But at the end of the day you look like an unfashionable tourist when you wear one.
11. Sport jerseys. If you need to rep your favorite sports team, wear a hat. When traveling, sports jerseys look cheesy and unpolished.
12. Bare feet. On the plane, bare feet are GROSS. Put on some socks.
13. Clothing with offensive logos. Skip it.
14. Skinny jeans. Not only is wearing your favorite pair of skinny jeans uncomfortable on a long-haul flight, but it can also increase your risk for deep vein thrombosis or blood clots. Opt instead for loose-fitting, breathable fabrics, and if you're pregnant or have a pre-existing medical condition, ask your doctor about wearing compression socks or stockings as an additional preventative measure.
15. Contact lenses. Airplanes are notoriously dry environments, boasting minimal humidity. If you're near- or far-sighted, consider wearing your glasses for the duration of your flight. Your eyes will thank you.
16. Religiously offensive attire. What might pass for church clothes in the States, could very well be considered immodest in other countries. Do your research regarding cultural norms before you touch down to ensure you don't offend anyone with your outfit.
17. Crocs. Unless you're Mario Batali, just say no.
18. Large purses. Leave your oversized totes at home (or at least in the hotel room). Not only do small, cross-body bags take up less space, but they're also less of a temptation for pick-pockets.
19. Your warmest sweater. Between the plane, your hotel room, and jet-setting around your destination, you'll likely be navigating multiple microclimates, which makes layering key.
