Overview
- An interdisciplinary team analyzed roughly 35,000–37,000 images of women’s clothing from 1869 to today, converting hemlines, necklines, and waistlines into quantitative measures.
- The model shows styles rise, fade, and return on waves peaking about every two decades, matching industry lore about recurring trends.
- Clear oscillations appear in skirt lengths across the 20th century, with short 1920s looks giving way to longer 1950s styles and then late-1960s miniskirts.
- Since the 1980s the data show greater variance and concurrent niches, with mini, midi, and floor-length options coexisting rather than a single dominant look.
- Lead author Emma Zajdela presented the findings at the APS Global Physics Summit on March 17, and the team suggests the same dynamics may inform other forms of cultural innovation.
