egretti, töyhtökoriste, sulkatöyhtö The lesser white heron; the egret.
A feather or plume, or feather-shaped item, used as an adornment or ornament.
1819, Lord Byron, Don Juan, III.77:

His turban, furled in many a graceful fold, / An emerald aigrette, with Haidée's hair in't, / Surmounted as its clasp ....

Young women attired often in nothing more than ostrich-feather aigrettes dyed in colors of doubtful taste ran nubilely up and down the marble staircases, chased by young men in razor-toed ball shoes of patent-leather.
