No, but I almost wish I had been if someone had been more honest!
I got quite comfortable in my first job, which seemed like a pretty relaxed place. I wore my septum ring occasionally, and later I got spiky purple hair extensions. No one appeared to mind, but I'm sure it's one of the reasons my boss seemed to go off me and start bullying me. I wish she'd just said that she felt I looked unprofessional or something rather than starting to pick me up on everything else! I'm pretty sure the hair/nose ring was part of what set her off, and she should have just said something if she thought it wasn't on.
At school my mate Katy and I got a talking to in the sixth form when she dyed her hair green and I dyed mine purple (but it was much brighter on Katy, as she had very light hair). It wasn't very permanent stuff, but the head of sixth form told us it wasn't appropriate, bad example to the kidz etc (it's not as though we were at all cool or influential!). Mind you, a few kids did appear with coloured hair streaks in the next few weeks. We probably would have been sent home if we'd been considered troublesome (our school was hypocritical like that) but as we were considered 'nice' girls, we got no more than a talking to.
