Beautiful Vintage Gillian Floral Silk Dress

There are no tags on this dress, but I am sure it is made by Gillian and the dress and lining are both silk. Flat measurements: Chest: 17", Waist: 15"; Hips: 17". The dress is in overall good condition. The only condition I could find is some small pinholes in the lining. They are not visible when wearing the dress.
