Middleton, 29, who will marry the prince on April 29 in London, soared as a fashion icon in November after the blue dress by designer Daniella Issa Helayel that she wore for the official engagement announcement sold out of stores within 24 hours.
Speculation is now rife in the fashion world over who will design Middelton's wedding dress, and what it will look like.
A survey by the Texas-based Global Language Monitor of fashion buzz words and phrases in print, on the Internet, and in social media, ranked Middleton the No.1. word for the upcoming season.
Singer Lady Gaga, known as much for her striking outfits as her hit records, was pushed into second place in the annual survey.
"Sheer" -- the trend for translucent fabrics -- came in third place, followed by "shirt dresses", and "sustainable style," reflecting a growing trend of clothing made of recycled fabrics.
New York fashion week starts on Feb 10, kicking off an international calendar of shows that includes London, Milan and Paris.
The words in the Global Language Monitor survey were chosen from the world fashion media, nominated by key fashionistas from around the world and tracked for their frequency and usage in English-speaking media outlets around the world.
