Vintage 70s Polka Dot Mini Dress, Built-In Bra, "Linda Originals" Montreal, XS

Own a piece of Canadian fashion history with this vintage 70s mini dress by "Linda Originals" of Montreal. Crafted from polyester in blue with white polka dots, this original piece exudes the mod look. It would look amazing with a pair of white go-go boots. The foam cups of the built-in bra have become hard and crumbly with age (see last photo). For this dress to be wearable, they will either need to be replaced or removed. There is a loose stitch or two in the front of the dress, where the bodice is connected to the skirt. Measured flat, pit-to-pit: 16.5" Waist: 14" I've found evidence of Linda Originals existing in the 60s and 70s. I've dated this dress to the 1970s because of the appearance of the care tag.
