Fallon was the son of a very wealthy banker from Connecticut. The first time Fallon saw an indie artist on YouTube wearing a polished bicycle chain around his neck, he knew he had to get an item like that for himself. Fallon's behaviour would best be explained as a ________ theory of fashion.

A) trickle-down
B) trickle-up
C) trickle-across
D) trickle-skipping

Trickle-up theory of fashion suggests that fashion trends start in the lower socioeconomic classes or subcultures and then are adopted by higher socioeconomic classes. Fallon's interest in adopting a style he saw from an indie artist on YouTube exemplifies this theory, as he is from a higher socioeconomic background and wants to adopt a style initiated in a more grassroots or subcultural context.
