Short and sweet: found Chanel Cosmic Violine on eBay for a decent price; bought it; wasn't sure I liked it; put it on and loved it. It is more brown-based than I thought it would be, but that doesn't stop the beautiful, red microglitter (shimmer?) from peeking through. It's definitely a polish I would keep for a 'classy' occasion. Two smooth coats and topcoat provided the glossy look below.

Would you shell out money for Chanel polishes or do you feel they are overrated?
