There was an ad that appeared in my mum's women's magazines, showing a woman in a little black strapless evening dress. The text said something like, "At last a towel you can wear without it showing through your clothes." I believed she had a beach- or bath-towel wrapped around her body, left on underneath her dress. Although I wasn't sure why.
