Lindsay Tweets Sam a Vulva Bug Picture?

Lindsay Lohan sent a picture to Samantha Ronson on twitter, calling her baby. The picture was a VW Bug with a vulva painted on the hood.

The picture is under the cut and is NSFW if your boss doesn't like you to look at car vulvas at the office. But what I really want to know is what the hell Lindsay is wearing in the above photo? I think that shirt is far more obscene than any car's paintjob.
