My mum was most definitely not supportive and caught me a number of times and even made me wear her skirt and boots, which I'd been "borrowing", for the day as well as trying to humiliate me by outing me to my favorite (glamorous) aunt by taking me shopping all of which is a story that I've told before.
My mum doesn't know that I still dress and I won't be telling her anytime soon either.
The funny thing is though, I'm sure my dad knew as he nearly caught me dressed once but it wasn't until he left my room after we'd chatted about something or other that I realised that there was a pair of stilettos still visible under my bed and he couldn't have not seen them, also when I was in the army my stash disappeared and the only person who could've done it was my dad but he never said anything to me or made a thing about it ever.
But my mum, NO.
