Saw a great one yesterday...
I was at a baseball game (MLB game, wont say the teams though) and this girl behind me, and left two seats had white shorts on, wearing a blue thong and the shortest top you could find (It was almost like a bra). The white shorts she was wearing were very short, yet baggy. So whenever she stood up (she was at the end of the isle) for others to walk by, and when I looked up I had some great views.
Towards the end of the game, her thong must have slipped to the side and oh boy did I get an eye full. It was so hard not to look. I couldn't take pics with 45,000 people in the stadium and all I have is an iPhone anyway so quality would have sucked.
Almost makes me want to buy the same seats again and hope shes a season ticket holder
