In the first five minutes of the film, the throughlines of Cher’s wardrobe are established: bright or rich colors, plaids, and some variation on the four Fs: feathers, fuzz, fur, or frills, which all tend to highlight her fussy nature and princess-like attitude. (…)
Her entire wardrobe suddenly changes almost exclusively to romantic pinks and lavenders as she tries to make herself into a better person, a person worthy of Josh.

This final bit of costuming illustrates why Clueless has had such long-lasting impact and has inspired fond memories for an entire generation of viewers.

It’s Cher Horowitz’s coming-of-age story, plain and simple.
