Nailing your airport/travel style is important because it's practical too. You want to wear something comfy but stylish, a matching track set is perfect. Layer it over a t-shirt or a tank so you can lose the top layer if you need to. A lightweight coat that you'll wear at your destination is a must for travelling light, a trench coat is ideal. A large tote to carry your travel essentials in is a necessity and great if you need the space come check in. Separate out the important stuff into a pouch for easy access. And don't forget a baseball cap for when you land.
