I love holidays in the Sun, but I don't always get them, so it makes no sense for me to have a large square of fabric sitting in my wardrobe for maybe years at a time, so I made the conscious decision to never buy a sarong again and instead have scarves (the dream being just one) that could double job.
While I still have a slightly torn and slightly stained sarong at home, I was packing light for this trip, so decided to test the scarf method.
I use a sarong on holidays to lie on on the beach or by the pool, brush sand of my legs and feet, as a scarf if I get cold, to cover sunburn, or as a skirt for short journeys from pool to bar etc. The scarf fulfils all these duties, and does the most important one better:
For some reason they don't make sarongs body length ...so when you lie on them your feet and the bottom of your legs are on the sand (if you are on the beach) or the plasticy cushion of a lounger maybe. A scarf (or at least the one I brought) solves this problem, by being a more rectangular shape and as it turns out long enough so that my sunblocked (and thus sticky) legs aren't in contact with anything icky.
