Here are some of the looks I found out there on the almighty internet, and my thoughts:
Floppy hat and sunglasses yes. Tank, sure. Mini and boots? I wouldn't recommend it, there's a lot of sitting on the ground and those boots may not be the most comfy for getting from stage to stage. She's cute enough but I just don't feel like this would be comfy for a day of wandering in the sun.
I feel like both of these work. Long dresses make for easy places to sit. Both ladies have their layers for when there's a nip in the air. They both have bags for things like phones, ID, cash and hand sanitizer!
Too much work...but she's a celeb, and I have a feeling that port-a-potties aren't an issue back in VIP.
Kate Bosworth though, she gets it.
And then there's always the "REALLY?" group....
