- Melanie Scheussler suggests a date of post-1540 for England, France, and the Low Countries; see Scheussler, "'She Hath Over Grown All that She Ever Hath': Children's Clothing in the Lisle Letters, 1533-40", in Netherton, Robin, and Gale R. Owen-Crocker, editors, Medieval Clothing and Textiles, Volume 3, p. 185. Before roughly this date various styles of long robes were in any case commonly worn by adult males of various sorts, so boys wearing them could probably not be said to form a distinct phenomenon.
