Vintage dress - Louis Féraud colourful patterned silk dress size 10

Louis Feraud Paris vintage button up dress. Size 10. Turquoise, purple, black, green, etc. Paisley and animal prints. Breast pockets. Long sleeves. Gold coloured buttons with purple ’gems’. One button is missing the ‘gem’. The skirt of the dress is lined. Approximately 48” long. Great vintage condition (other than the button.) I believed it is silk but there is no material tag.
