Cute As A Button is one of my favorite Essie's ever and I really liked Temptation when I wore it but didn't make the connection to their similarity until it was pointed out to me by some readers. They actually are super similar, but not quite dupes.
The Essie is a smidge warmer/more coral and the Sally Hansen is a bit more opaque and is a total crème where the Essie has almost more of a jelly-crème finish. Both are excellent polishes. If you're having trouble finding Cute As A Button, try Temptation. You should be able to find it in stores wherever Sally Hansen Complete Salon Manicure is sold.
