One of my daughter's teachers, who was a big inspiration in her life, once made the "amazing $6 gown".
She bought the end of an expensive fabric--same kind as used in wedding gowns (I forget what it's called--a fairly substantial and glossy fabric), but in a shade of royal blue, on clearance for $6.
She already had thread and other supplies.
To save on expenses she didn't bother with a zipper. She has to wiggle into it.

Sowed it up a few days before a social event and it looked stunning.
With her level of sewing skill, it looks like what would cost you a cool $600 at Nordstrom's.

Very artistically talented young woman.
