Illamasqua Collide is what began my descent into neon pink madness this spring. It's a very creamy cool neon pink which seems very dupable in color, but the formula is absolutely fantastic. This polish doesn't need undies, doesn't chip; it does dry matte like any neon should, but I have not had any issues with staying power.
Illamasqua polishes are a type of drug to me, they are high end polishes and the price reflects that; their formula is addictive and amazing (most of them, anyway...I'm looking at you, Load). They have a stock of common colors, even 5 shades of bright red and I almost want to buy all of them! Why? Because I know it's going to be a breeze to apply and they won't chip for like a week. Every day I fight the urge to put on Illamasqua colors because I reach for them every time I want to do a manicure... that sounds a little weird, but they are seriously addicting to me.
Have you tried Illamasqua polish yet? If you did, what was your favourite?
