bralette
n.— «The forms “prettiness” now takes, which include “bralettes” for girls as young as three, as well as the language used to describe appearance in girls’ magazines directed at readers from five up (“hot, hot, hot”), give the game away. This sexualising pressure places children at risk in a number of ways.» —“Adult world must let girls be girls” by Emma Rush Sydney Morning Herald (Australia) Oct. 10, 2006.
