I don't normally spend $18 for a bottle of nail polish. That said, I was captivated when I saw Bobbi Brown's limited edition Twilight polish. In the bottle, it is a deep, plummy,chocolate brown & has a wonderful shimmer, great color for Fall. On my nails, I can't see any of the shimmer unless looking at it in direct sunlight (the color isn't flat, it has a nice glow, but definitely not shimmery unless in direct sunlight). In fact, on my nails, it looks much more brownish/black than it did in the bottle - not a bad color, but not what I was expecting. Overall, I would say the formula wears well (I use base & top coat and don't wear gloves to do dishes) - I've gone four days so far without a chip. I wouldn't re-purchase because the color wasn't what I was looking for, but I will wear this for Fall/Winter.
