Unbelievable- this stuff has got great lasting power, even without a topcoat! I work in a hospital, so I am constantly washing my hands. Needless to say, it wreaks havoc on any polish I wear...except this! I put 2 coats( even though it said one coat color) and ran off to work. 4 days later it's going strong, it's just got some chips today, and that's only because I was cleaning with bleach water. My other hand that wasn't dipping into the bleach water is still perfect. I bought this off ebay, so the price was about the same as I'd pay for Essie. Must Have Pink is a bright, candy pink with a slight blue sheen in certain lighting. It goes well with my light olive skintone- I even look like I have a tan! I can't find this color on Sephora, or anywhere else except Ebay- maybe it's been d/c'd? I would definitely be checking out other Dior Addict polishes!!!
