I’ve seen several people suggest sarongs as a great multi-purpose item, but I’m not sure what kind to get. The ones I’ve seen at the stores are the sheer swimsuit cover up kind, but they don’t seem at all substantial enough to function as a robe, etc. I looked online, and saw them in several different sizes, materials, etc, and was hoping someone could give me an idea of the best material to look for, what size seemed to work best, and a good place to find one. Is online going to be my best bet?
