It's by Cow Cow and I've heard their sizing is all shot to pieces now, so I haven't bothered buying anything else from them. Still, I love the colour and the print. My necklace was also a unicorn pendant, I bought it years ago and can't remember ever wearing it before!
Just before the zine fest started
Here's the badge I was wearing, my friend Jane sent me it for Christmas. It says "Wearing whatever the hell I want" on it. Appropriate for wearing with a unicorn dress!
