Sarongs can function in many ways and can have various styles & patterns & colors. In my opinion, they are somehow an exotic clothing. They look very lightweight and comfortable, too. I don't know what you'd do, but I'd wear them especially on seaside during summer to protect my legs.
By the way, you don't need to wear sarongs just as clothing. You can also use them as headscarf, shawl, belt or even tablecloth! They are multi-functional ;)
