Lady Gaga wears a sexy bikini costume during her July 2, 2010 Monster Ball concert in Boston

One of Lady Gaga’s many, many costumes warn during the July 2, 2010 Monster Ball Tour concert at the TD Garden in Boston, Massachusetts. The concert was a two-hour show that featured no less than thirteen costume changes for the entertaining pop superstar, including this sexy two-piece bikini-style outfit matched with Gaga’s infamous bright yellow hair color.

The Monster Ball shows are a narrative that begins with an escape from New York City and follows Lady Gaga as she travels through numerous settings and backdrops, fighting monsters along the way, until she ends up at the Monster Ball. The Monster Ball is a place the singer proclaims will “set you free” and where “all the freaks are outside and I’ve locked the doors.”
