I went from waist-length hair to pixie crop and loved it. I'm def not a pretty elfin type but it looked quite good. I did have to change my style of dress quite radically in order to look funky rather than dowdy and I occasionally had a striking colour put in to jazz it up. I got lots of positive compliments from strangers - all women wanting to know where I had it cut. Interestingly family and friends never really liked it as much as I did. Grown it back out into a longer style now just for a change.
Unless your hair grows extremely slowly and you don't think you'd have a complete meltdown if it wasn't great, I'd say go for it. But make sure you go to a good hairdresser who would be able to reassure you that it would suit your face.
Geordieminx - that's a fab haircut. Not in the least Pat B.
I felt very exposed with short hair. Hairdresser told me i looked liek drew barrymore with the right face shape and features for short hair,,,I felt liek a butch freak for about 5 months. horeendous will never forget it. when I saw people i hadn't seen for a while they said "ooooh haircut". they didn't know what to say. but usuallythey said "it'll grow".
i have a gawgeous friend who really shines as being gawgeous with v short hair. i'm v jealous because i know it would never suit me (perhaps an injudicious comment by a hairdresser about not wanting to make me look "too butch" has been taken too much to heart )
i think you have to be totally honest with yourself about your looks, e.g. how do you look with hair scraped straight back off your face? if okay then a crop could work.
