The T-shirt study by Gross (1983) found that the presence of printed material on T-shirts seemed to undermine the selection influence of physical attractiveness. Participants rated physical attractiveness as less important when the T-shirts had printed material on them, suggesting that the material drew attention away from physical attributes. Attachment styles, familiarity, and personal traits were not directly tested or influenced by the printed material on the T-shirts.
