What was Sienna Miller thinking?
Sienna was spotted during the Isle of Wright music festival in the UK dressed like that!
Where should i start from? The combination is disastrous! The hat, the cropped shirt [ as if she went into a crazy fit & cut off her shirt with blunt scissors! ] & the silly black shorts!
I guess the best item she's wearing could be the jeans vest!
Sienna's got a great body & has a beautiful face ... why dress like that!? Why!?

This isn't the first time Sienna is spotted is something ugly ... check this out.
