You'll be able to tell from the crest. That was our Centenary season so the badge has 1904-2004 on it. I've discovered that my 2000/01 away shirt was bought during my phase of wearing loose fitting shirts, so despite being a bit taller and more than a bit bigger it still fits. In terms of it being fitting, the season we wore it Orient made the playoff final, and at the end of the season the Hull City manager was the last English manager to have won a major trophy.
