Vintage 60s dress does the 20s style tennis dress. I don?t think this is literally a tennis dress but the style is reminiscent of that era. There are no tags, but it feels like a lighter weight stretchy polyester. Blue and white variegated stripe top that is crewneck with a white panel. Insert to make it look like a V-neck. Removable coordinating sash for a little waist definition before falling to a solid ivory skirt. laying flat measures approximately 38 inches shoulder to him, 17 inches armpit to armpit and 13.5 inches straight across the waist. Based on the measurements, I am listing this as a size small but please double check measurements to ensure the proper fit for you.
