My New Years Outfit....................

I might as well post this one before it's no longer relevant. The dress was a Christmas gift, and it's by Stylestalker, I love the teal colour, the crepe fabric, the hood, and the zippered pockets. I'm going to wear it to Big Day Out next weekend, but with my combat boots, not the beau coops shoes in the picture. Anyway, I have a slight problem. Somehow on New Years, I managed to get white chewing gum on the back of the dress and it's noticeable. Not sure if this is right, but I was thinking of using some cooking oil to remove the gum, then once that's gone use something else to remove the oil???? If anyone out there has successfully removed chewing gum from fabric, please share your methods - thanks :)
