:rofl: Okay I just did a google search.. Apparently what is a singlet in NZ is a tank top in America.
usually nothing. sometimes at my parents' house, I'll wear some boyshorts and a tank top of some sort. or a white T.
in the winter I sleep in a fluffy robe. In the summer I sleep naked or in some panties. I haaaaaaaate sleeping in a shirt though. I don't know why.
