Damn! I have crazy, mad, Rain Man-like skills when it comes to remembering MAC colours and colour stories and you have me stumped. Let me look into my "network" and see what I can find. You may not want it after the time that has passed. The product may have turned.
A close second alternative is to go to www.threecustom.com
(to go straight to the lipstick matching service). They reproduce lipsticks. They may have Bardot on file. Won't you be a hero? Your mom and aunt will LOVE YOU! I'll get back to you.
