Vintage 60s Size 5/6 Dress Lorrie Deb Colorful Floral Maxi Taffeta Belted Ruffle

The dress does not have the fabric tag in here, but feels like a silk taffeta. It is soft like a silk satin but loud like taffeta. 
Labeled as a size 5/6 and made in USA ILGWU. 
It looks to be in excellent condition for its age.
I did notice that the top clasp on the belt needs to be re sewn with needle and thread.
I do try to disclose all flaws and this dress may have a very small spot that needs treatment, if at all. 

Measurements when laid flat:

Bust: 15.5 in.
Waist: 12 in.
Hips: 21 in.
Length: 53 in. 

Thank you for your interest and have a great day!
