Under the shatter nail polish, I applied 2 coats of Sephora by OPI's It's bouquet with me. I ended up not liking the shatter nail polish as much as I anticipated on liking it. I honestly think it's only appropriate for Halloween, but it does what it claimed to do. It crackled within 30 seconds and dries fast. It looks much better with a top coat. With one coat of the shatter nail polish, it leaves a cheetah print and with two coats, it leaves a more defined crackle, like in the picture above.
Metro chic is a taup-ey, muddy color, with a splash of purple. Unfortunately, the formula is quite streaky and it usually takes quite a few coats (3-4) to get it to an opaque shade. This is my go-to nail polish when I paint my nails. It's very flattering on most skin tones. I will be repurchasing this very soon!
