Unisex style t-shirt ideally - polo shirts are too warm and ladies shirts are always 'slim fit' - ha! Our breed clubs don't do anything like that as far as I've ever noticed at shows, though they are good for little figurines and other items. :-)
Waggitt do have some, but to be honest the Cavalier faces are not brilliant for the most part (though I've discovered some cartoon ones on their site which I must resist.....)
