Travel outfits are important. You wanna look good (generally speaking) and be comfortable/warm, because eight hour airplane trips in a freezing airplane sitting next to a screaming kid in a tiny seat is not enjoyable in skirts and flip flops. Go for layering and be sure to keep your jewelry to a minimum. You do not want to be that bitch that makes everyone wait twenty minutes in the metal detectors because you chose to wear all your stackable bracelets on one day.
For shoes, make sure you wear comfortable shoes! My all-stars are my go-to, although flats (they're quick to take on and off for security) or boots (when it's cold, wearing boots is a very good idea) are also good options.
