Paris Vintage Floral Slipdress

Purchased from Petite Chineuse in Le Marais in Paris and I wish I could keep it but it’s a little small for me. Best for a size zero, has a little stretch and adjustable straps. Bust is 32” and waist is 26”. My best guess is this piece is nylon from the 90s but there are no tags. Reminds me of Rouje Paris or Reformation Vintage on Melrose or maybe even Betsey Johnson.
