What a great save! You made melonade outta melons!
It look great as a top and I agree with Bladerunner that you could turn the bottom half into a skirt. If you have some of the pink fabric left over you could add a casing at the top with an elastic.
You did do well by the pattern though; the style lines in the pattern picture are very straight. If you wanted to do the pattern over again as is, you could just wear it with a nice belt and that would help define your waist.
