The incidence of candidiasis in two groups of voluntary participants wearing tight and loose fitted dresses was investigated by both microscopic and cultural techniques for a period of two months. Two-thirds of the positives by stain and culture were recovered from those wearing tight clothing (P < 0.05). The findings suggest that tight clothing can predispose the wearer to candidiasis, an organism that can cause vaginitis. (Am J Public Health 1982; 72:176-177.)
