Carnevale di Venezia, Italia I think the plain white masks contrast quite nicely with the vividly bright colours of the costume. I think that tulle stuff can be found at most craft stores.in most colors too.
Reminds me of a scene from Phantom of the Opera. "They say that this youth has set my Lady's heart aflame! Fop) His Lordship, sure, would die of shock! Fop) His Lordship is a laughingstock! (Confidante) Should he suspect her, God protect her!
