Vintage 70s/early 80s polyester sleeveless floral print dress

This is one cute dress! Check out the pretty floral print - perfect for spring! Tag says Brand is Anne Haley. Machine washable 100% Polyester. There is a ROBIN zipper partially down the back. It think it fits around a size modern 8. It almost looks like the sides have been expanded a tiny bit. I am not sure if they are original to the dress or not. There is one small hole that was repaired on the side. Please see last photo. There is 3" of fabric sewn under on the hem. Dress is in nice condition asides from what I just mentioned.
