TZEITEL'S WEDDING GOWN
Her wedding dress and veil were beautiful, and especially ornate for a people who were so poor.
She even wore white shoes, which I'm sure were a luxury is Tsarist Russia.
I don't believe that it was Golde's wedding dress, not only because that it was in such pristine condition, but for the fact that it fit Tzeitel (who was taller than her mother) perfectly.
Did Motel make it for her? Highly unlikely; Tevye and Golde would have objected something so "intimate" before they were married.
Maybe there was a seamstress in Anatevka who made the dress and veil for a low price.
Motel and Tzeitel had a son; I hope they later had a daughter who would wear that dress on her wedding.
