I think I want one, but there is something niggling me.
Not sure what
, can anyone tell me? 
I had one 20 years ago, maybe it's the feeling I should not try to dress like I did in my 20s?
Something inside me is saying :"no!" . Is it my inner Daily-Mail-reader telling me to start wearing fitted dresses and nude court shoes?! (Never!)
I really want one, but need to know what this niggle is....
