Sparkly bit on a gala gown

I believe the answer is:

sequin

(Other definitions for sequin that I've seen before include "Italian gold coin" , "Glittery decoration" , "Sparkling disc on a dress" , "Ballroom dancer's sewn-on sparkler?" , "Shiny decorative disc" .)

I've seen this clue in The New York Times.
