Prepare for the Worst with These Outfits
When flying, you can’t predict the weather based on where you’re coming from. You’ll be going through the clouds above various cities or countries that may be experiencing different weather conditions. So be sure to dress in a way that can weather any storm.

To do that, simply wear several layers of clothing. Then you can take off some layers when you’re hot and put them back on when you’re cold. It may mean you’ll have extra items to hold during the flight, but that’s only a small price to pay.
