Lady Gaga's Appearing At Lollapalooza 2010, But What Will She Wear?

The lineup for Lollapalooza 2010 was announced this morning and it included one major theatrical diva: Lady Gaga. The summer music festival takes place in Chicago (Grant Park to be exact), but at that time of year, the venue doesn't quite hold up to the area's "Windy City" nickname: it's scorching hot outside.

Gaga is known for wearing large hats and wigs, plenty of makeup and fabrics that tend to contain metal details and outer space influence. This begs the question: what in the world will Gaga wear to stay cool at Lollapalooza this August? For research, we pulled out our summer festival yearbooks (click on the picture below to peruse) — which included the Glastonbury Festival and the Much Music Awards — and pinpointed a few memorable Gaga fashions. When this singer brings the heat, she really keeps it hot!
