There are 3 key things you want to keep in mind when figuring out your own perfect travel outfit:
1. Layers. Wear layered clothing so you can easily dress for the temperature you find yourself in, and there can be many extremes from point A to B.
2. Comfort. Make sure all the pieces you’re wearing are comfortable and easy to move in. Pants that dig into your waist for hours while sitting is never pleasant.
3. Carryall bag. If you’re able to take a bag that acts as a purse and a carryon, you’ll feel much more organized, and won’t have to keep track of as much.
If you want to be really strategic, and pack light, try to make sure that whatever you’re wearing on the plane can also be used on other days while you’re away.
