Kate has the same thing about orange. I like blue on other people. I have blue eyes and in fact blue really suits me. But I hate wearing it and in particular don't wear light denim.
I am coming around to some blue - I have a maternity dress that is navy bordering on black, so that's as close as it gets at the moment. And I'm wearing more purple which is the other side of blue I guess.
I love blue precious stones - Ceylon sapphires and aquamarines. I love a rich sapphire colour. But wouldn't wear it in a pink fit.
