If there's anything her time at Torchwood taught her, it's that if you have a chance to celebrate survival, you should take it. So Tosh is here, casually dressed in a purple top and jeans (http://t3.gstatic.com/images?q=tbn:ANd9GcTFc5v99cYez2TVlT5kXe2PM6SLVUuRkXYxbg-fKB-9Vey28Frm), and a leather coat, because it didn't really sound like a dressy kind of affair. She snags a beer and finds a good vantage point from which to people watch.
