Meaning - transvestite? Transexual? Cross-dresser??
Why they feel the need to label everyone is beyond me, but my reply is simply "alternative" but I prefer saying "just being myself and wearing whatever I like". Some are happy and accept that, some others can't get their heads round it, but the majority have always said "good on you".
Of course the more men we get to wear skirts, then we can drop the "alternative"

Also just had a day out in London on the train from the NW and not one comment or even look - just as if I'd worn jeans (sorry to swear there) all day. Great!!
