Short sleeve summer dress found in the walls at Ruby's Place

Photo of the full dress on a table. The dress was found in the walls of Ruby's Place during restoration work. It is a woman's lightweight summer dress from the 1930s and is full length with short sleeves. It has a tie that would have tied around the waist, maybe towards the front or the back. It has a series of buttons along the neckline. It's a lovely shade of sort of pale purple or lavender, and it's in a bit of a check pattern
