This lipstick is a dupe of a dupe. It has exactly the same color as Fanny Serrano's Swiss Kiss, which, as established by the Girl with Glasses, is a dupe of MAC's Russian Red. (Somehow I'm not surprised, what with Fanny Serrano owning the F21 brand and all. XD)
While Swiss Kiss costs P199.00, Wild Cherry only costs P150.00. I suppose the main factor in price difference would be packaging, as the first lipstick comes in a shiny metallic aqua blue tube while the second lipstick is dressed in this simple black number:
I did not have my camera at the time I swatched WC next to SK, but you can see from GwG's post that they are indeed the same. Besides, there's usually an F21 stall next to a Fanny Serrano stall anyway, so you can try swatching them yourself to see how similar they are. :D
I'm more of a nude fan, but I can certainly see myself using this lipstick for when I want to shock people with a pop of color.
