I have this in one of the colours from the nude/stripped collection and it's amazing.
It is a perfect nude, and it lasted for over a week before chipping. It's what I had hoped OPI Samoan Sand to be - but at half the price. Two coats and it was opaque, which is just what I was after and I was so surprised as it's a nude. I'll try more colours but I am surprised everyone says they chip as mine lasted so well.
I have only one of these nail polishes in Chiffon Chic. I received this for my birthday from one of my best mates. I have only used this polish once and I absolutely hated it. The formula was quite thick and I found that it didn't apply on my nails evenly. I found that it also chipped away very easily and didn't last that long. For me I wouldn't purchase these nail polishes due to what the formula was like on this one plus I have far to many.
