I was putting away some recently purchased nail polish (seems like I'm doing that every day ha!) And I noticed that wet-n-wild gray's anatomy and my newly purchased sinful colors let me go looks almost the same.
As I held the bottles up there was some slight difference. Let me go has more of a pinkish-gray duochrome while gray's anatomy is more of a purplish-gray duochrome. However they are both the same price at $2 at Walgreens. Gray's anatomy may be easier to find as wet-n-wild polishes are sold almost everywhere. I've only seen sinful colors at Walgreens. If you can't find one the other will work just fine. ツ
