The most distinctive dating feature is the widespread use of boudoir caps and loose, flowing nightgowns/loungewear, which were highly fashionable in the 1910s and early 1920s. The presence of long, unbobbed hair on several women further supports a date before the mid-1920s. The setting appears to be a summer retreat or camp.

They are all wearing light-colored, loose-fitting gowns or robes and matching boudoir caps, suggesting a slumber party or a summer camp setting. A sign partially visible on the building reads 'Summ...'.
