Graham Shepherd really had a lot of guts for the costume he'd chosen to wear at the ball. His Robin Hood costume was quite "old-school," and quite authentic as well, from the bow and arrow right down to the red tights. He had fairly skinny legs, legs which women had told him - often jokingly - they were quite jealous of. Then again, it was a costume he liked to think fit his personality fairly well. He didn't exactly steal from the rich and give to the poor, but he did try to tell the stories of the less fortunate, or the underdog - not the spoiled, rich and fake. The tights tended to ride up a bit at times, but they did make the costume, so he did his best at suffering through it.
It was also rather brave of him to attend the ball on his own; going stag. Then again, he enjoyed meeting new people, and it would be a fun place to mingle. Should he find an angle for his story while he was there, all the better!
