Fashion experimentation started to become popular in the 1940s, and loungewear was considered the perfect clothing category to take risks in. Many women wore robes that cinched at the waist to emphasize their femininity, and the majority of them had zippers or wrap-arounds to make the garments appear as if one was wearing a dress. These came in a variety of prints, from polka dots to florals and lengths, with some coming down to the ankle, others draped over the knee. While robes were considered appropriate if a woman had guests over, lounging slacks, which were flowy pants made from a heavier material than regular pajamas, were popular for solitary leisure, and were often paired with a blouse, robe, or tunic.
