Formula X Intensity Nail Polish $10.50 // Link
This pastel, powder pink shade took three coats for complete opacity, but seven days later it's still going strong with only one tiny chip. Pastel colours are notorious for early chipping, but I was so impressed with this one. The Formula X brand has had some hit and miss reviews, but all of the polishes I've tried from them so far have been pretty good, so I don't know whether it's just a few particular shades. I plan on doing a whole post dedicated to FX, so let me know if that's something you would like to see.
What are your favourite opaque pastel shades? Spring's coming up I need some recommendations.
