Rose Tea Gown

Vibes of an 80’s imitation of a 50’s tea dress I have no idea what fabric this is but it’s a heavy weight shimmery silky fabric. The dress is clearly hand made and the one-shoulder strap is more decorative than structural, as it is sewn to the dress rather loosely. This was only worn once by me but bought second hand. only three small stains. (shown in pictures) Reflected in price. No idea how to wash it but it was dry cleaned after I wore it. Dry cleaning caused press marks of string under fabric. If you want I could hand wash it? but I kinda don’t wanna mess with it any more. approx. size 6 pit-to-pit: 16” waist: 15”
