Mad hatters

If there's one feature of the Sevens which can always be relied upon to inspire shock and awe in equal measure it's the head gear. Sevens fans are notable for their ingenuity, and can turn anything from a pizza box to a rubber glove into a serviceable hat. And for that extra special something up top, well, you can't beat a condom.

You may not find these beauties on sale at Harvey Nichols, but you can be sure they will only cost you your dignity.
