The bizarre fashion trend where young girls dress like their grandmothers. Grey-dyed hair/highlights, knitted accesories, and sweaters maybe classified as "biddychic." Trend may have originated from recent high fashion runway shows. Kelis, Kate Moss, and Lady Gaga have all rocked biddychic.

(biddy:an old lady "lil ole biddy" chic: fashionable)
Her hair looks like she's naturally greying; I wonder which local salon specializes in biddychic.
