Essie - Cute as a Button Dupe?

I have been lusting after Essie's 'Cute as a Button' for quick some time now. In the bottle it looks like a regular hot pink, however on nails it is a mix of coral and sunshine pink. It's a gorgeous combination that reminds me a fruity cocktail.
However, after deciding that I spend far too much money on nail polishes, exhibit A, ladies and gentlemen:

I began my quest on find a 'Cute as a Button' dupe and the closest I've found is '17 - Pink Grapefruit'. I absolutely love this colour, and after putting the two bottles of 17 and Essie next to each other in Boots yesterday, there is very little difference in color.

It's a lot more pink in color than my camera is willing to show. It is very similiar color to the big Vaseline lips tin.
I don't own 'Cute as a Button' so I have nothing to compare the color to when it's on the nails, but it is a very close shade indeed. And for £2.99 as oppossed to Essie's £7.99 it's a complete steal!
