I bought a necklace about a year ago from someone I knew absolutely to be an ex-MAC employee but I couldn't really explain why I wanted to have it.
I've never worn it out of the house as I feel kind of funny about it. I'd probably be sort of embarrassed if someone recognised what it was, as if I was saying "Wow! Look at my make-up - I'm such a pro!" and I know I'd feel lame explaining what it was to someone who didn't know. My husband always laughs when he sees it.
Anyway, I'm glad I have it despite that.
