I bought some chunky knit over the knee socks from asos (2 black and 1 grey) and tried them on, nearly wore them a few times, always bottled it.
Did wear my grey ones folded over to below knee and wore with my riding boots and was very :) but did not seem to be able to go 'all the way'!
So today, I wore the grey ones over leggings, with a floral dress and with my knee length winter coat (fastened!). At first I was all
and
and then I opened my coat....and I couldn't help having this wicked smile on my face! It was alot of fun....I implore others to give it a go 
P.S plus DH rather likes it too
