I saw in a Ferrari store a Schumi kid-sized driver "pyjama" (as I'm not sure that combinaison in english doesnt mean anything else than a tiny pice of silk..)
... maybe you can also buy a Hawaian Tropic Girl string (obviously new so I mean not be worn before

)
Seriously wine is a good idea, but also some food stuffs as it's the best that we do. Just give me what they like, I'll tell you where to find it !
