Looking for a movie that came out around late 80s early 90s

[Kristie0603]

t was probably a TV movie from the late 80s/early 90s, and I'm 99.9% sure it was a Disney movie but obviously I have no way to prove it

The movie was about a teen or tween girl who would always change her outfit as soon as she got to school - she'd leave the house in something boring/frumpy to fool her parents, and then as soon as she got to school she'd change into like a mini and a boob tube and frizz up her hair..

Then one day she forgets that it's Yearbook Picture Day but she's already changed into her 'cool' outfit and it's too late to change so she ends up getting photographed like that. I even remember that the camera kept clicking even as she's getting up from the chair..

I remember ONE line from the movie and one line only, something her friend says to her in the cafeteria: "--and that girl is 100% pure polyester."

I *think* she was a brunette. I *think* she wore glasses..

NOTE: It's not that episode of Degrassi Junior High.. Or that Shannon Elizabeth scene in Scary Movie..
