look up any word, like hipster:
 
2.
A girl (or guy) who styles and models herself after lead singer Hayley Williams of the band Paramore.

To be a Fayley generally requires red hair (in one of Hayley's many styles and colors), yellow skinny jeans, to be incredibly thin, wear lots of New Found Glory shirts and septum piercings. This is a huge stereotype so even having one of these will result in you being named a Fayley.

Fayley's are generally hated for their looks, but overall, aren't always bad people.

A website known for aiding Fayleys is HayleyFashion.
This website will search and find any place you can get specific items worn by Hayley Williams. It is a very informative website, and is easily one of the better sources for all things Hayley (style-wise).

A 'Fayley' is someone who tries way to hard to look like the amazing Hayley Williams of Paramore.

Her style is her own and you will not be considered a fayley if you are inspired by her and perhaps have small elements of it in you're everyday style, however you will be considered a fayley if you dye your hair bright red and then try as hard as possible to dress, act or speak like her.

If you do try to hard you are a fayley.

Person 1: "Whoa what a fayley"
Person 2: "I know what a sad life she leads, I mean Hayley is amazing but these fayleys just ruin her unique style."

Person 1: "I'm thinking of dying my hair red, but a subtle red so I don't look too much like a fayley, even though she is my inspiration."
Person 2: " I totally agree. Be careful if you're dying hair red because if you look like a fayley I don't think I can be your friend anymore."
Person 1: ":o"
