Fashion X-Men Powers

I'll fess' up.  I'm afraid to say that there is one fashion territory which I sadly am unable to run towards with open arms, the way I do towards most things.  That is non-silver/gold/platinum metal jewellery. i.e. the sort of metalware you don't pay a lot for in high street jewellery.  Why?  I have a X-Men freakish skin condition that means as soon as I so much as touch any sort of metal that isn't pure gold or silver, it goes red and blotchy within minutes.  I learn the lesson of this freakish genetic oddity when I was in maths class in year 8 and was tapping my metal Parker pen against my cheek whilst trying to work out some algebra only to then have my friend point out that my cheek had turned an attractive blotchy red.  Nice. 

So my love for plastic jewellery is not because I'm a) cheap and b) well into Fisher Price.  There is bodily necessity attached to it.  Bangles especially are my weakness.  So my Monday eBay find in the form of this Peter Jensen for Topshop bracelet (how did I pass this by?) that I'm determined to have scares me a little for two reasons:
a) I spy cheap metal in the links and b) I spy red blotchy wrist in the future because I simply have to have the perspex blue skirted figures dancing around my wrist to remind me that the world is a nicey nicey place. 

This personal body affliction of mine made me think of what other bodily barriers people have (bar weight and body shape... that's a whole palava that I don't even want to go into) that prevents them from PHYSICALLY wearing/donning whatever it is they want to wear/don.  I can't be the only freakish one.  Fashion-X-Men, please step up and tell all.
