The second bride chose the same simple sheath dress, but provided ~$1000/yard! heavily beaded and sequined Venetian lace and we used a beautiful organza fabric for the train - gorgeous!
The second bride had originally requested red satin roses be added to her dress. I managed to convince her that red roses would be distracting and look like a quinceañera* dress and I only had to add white satin roses to the top of the sleeves.
Does the fabric make a difference? You decide!
(*Quinceañera - celebration of a girl's 15th birthday and the transition from childhood to young womanhood. Traditionally the girl wears the equivalent of a wedding ballgown, but usually in pink.)
