It must be Pride
After all, that's the only time this happens to me. And it sucks because it means that tomorrow in the big parade I may have no choice but to wear a shirt. Stupid sunny dyke march.
The bra- and tank top-lines provide a nice contrast (although what you see in the picture is nothing compared to what it looks like in real life) but are also evidence of my not having gone completely topless. For the first time since my first Pride when I was 16, I covered my boobs (although I did lose the top and wear just a bra for most of the march). I must be getting old.
