Paneled Linen Blend Midi Dress

My gut told me to return this and I should have listened. That was originally because of the difficulty of removing the wrinkles suggested it was low quality linen to begin with. I should have trusted my instinct and returned it then. The quality is Confirmed awful. After wearing for a few hours, I washed it gentle cycle and laid flat to dry as per the instructions. Now, 4" of the seam is undone. For the price, this should not have been disposable. Since when do clothes need to be covered by a warranty? I am deeply disappointed and may be reaching out to Nordstrom to return if at all possible.
