Hi and welcome!
You can make anything girly. Many members paint theirs, but I don't like things that are permanent (I get bored easily), so I use double-side carpet tape and fabric. If I don't wrap them (I have a Twist that is a deep wine color I like) I decorate the tank or get a cool drip tip.
There are vendors who sell eGo-type batteries that are already decorated, but unless you see one you cannot live without, I highly recommend you skip them. They are very cheaply made and don't last long - although you can buy them in bulk from FastTech and expect a high failure rate. For a first kit, I strongly suggest brands like Joyetech and Vision, however the iTaste is currently a hot toy, so I imagine people who have one will tell you more about it.
Anyway, "blinging" is fun!
