My best friend growing up was named Hayley, she's now in her 20s (if she had been a boy, it would have been Hayden).
She was very intelligent, quiet, polite and well-behaved, if a little bit over-sensitive. But because of this, I don't see the 'chavvy' side that everyone else does.
She occasionally got the nickname Hayles or even Hail-stone! (both of which she hated, so only went by Hayley)
Although she liked her nsme, she said that even her extended family often got the spelling wrong (Hayley, Haley, Halley, Hailey, Hayleigh, Haileigh, etc)
