Donna's Miss Twin Peaks Dress

 

Donna selects an off-shoulder black velvet dress with a red satin bow to wear to the Miss Twin Peaks Contest (episode 28, 2.021, Miss Twin Peaks). 

This dress appears to have been made by A.J. Bari. It features three folds of satin at the shoulders and a slit in the back of the dress, at the hem. It zips in the back. I found a similar dress from another label, but it did not feature three folds of satin.

Note the slit in the back of Donna's dress.
