Hello, I came across this stunning apricot colored (velvet???) dress and jacket set. I got this from someone who said this is from the 1930s but I have my doubts. the dress itself is sleeveless and skirt part is pleated. The top/jacket has matching fabric buttons and buttons at the cuffs, Sadly, these pieces have stains on them and I was wondering if anyone knows how I could take them out, and if anything is safe with this type of fabric? Thank you very much for reading.
