Stuff your socks
Originally invented by the US marines, this hack is used by flight attendants everywhere to make sure that they can grab a whole outfit in one go, swiftly. It’s called a Skivvy roll, and saves masses of space in your luggage, which you can then use for more souvenirs.
First, you take a shirt, a pair of underwear and a pair of socks. Then you fold the shirt and underwear together and place them inside the socks. A single outfit, all in one small place. Check out a YouTube video on how to make a Skivvy roll to ensure you’re not completely lost.
