There were costumed Sardinian dancers during the wedding's cocktail hour, i scalzi. Barefoot as is tradition. The earliest Halloween costume I can remember was as a Sardinian (miniature) woman in costume--I definitely stood out from the princesses and GI Joe's that were with me in kindergarten, and maybe confused a teacher or two :)
p.s. check out the guys balancing a shot of vernaccia on their heads while dancing!
