SKYN has two lines of ultra girly laptop covers, the floral prints in the Eva Collection go for $40 and come in pink (as you can see on the left), blue or purple, and the bright solid colors which are currently Lilac, Pretty Pink, Lime Green & Ocean Blue and cost $35. You can also choose to get a monogram of Swarovski crystals on any of the solid colors; that'll run you an additional $5.
All of SKYN's covers are glossy, attach to the surface of your laptop with an adhesive and are reusable, and they have a sizing chart to help you pick the one that's right for your device.
