The word tawdry is one of the classic Interesting Etymology stories.
The main sense of tawdry, dating from the seventeenth century, is 'showy and cheap; gaudy'. This sense is a derivation of the earlier noun, meaning 'lace worn by women about the throat'--a common fashion accessory in the sixteenth and seventeenth centuries--itself a shortening of the mid-sixteenth-century tawdry lace.
This tawdry lace is short for Saint
Audrey lace. Saint
Audrey was a queen of Northumbria and the patron saint of
Ely who died in A.D. 679; her name in Old English was
Aethelthryth. According to tradition,
Audrey died of a throat tumor, which she considered just punishment for her youthful fondness for showy necklaces. Thus, Saint
Audrey lace. (The lace was sold at an annual fair commemorating St.
Audrey's in
Ely, which probably strengthend the association.)
