The suit is in wonderful condition for its age and doesn't look like it was worn much. The fabric is a sturdy soft cotton mod floral print in orange, hot pink with off white flowers. Spaghetti straps with a center spaghetti bow.
The top is self lined and very well constructed with reinforced seams that keep the cups in shape.
There is no icky old falling apart foam inside the cup.
The top has double spaghetti straps that adjust at the back to size and there is a back metal hook closure.
The bottoms are also in very good shape. The elastic is still strechy and snaps back into shape. The bottom is lined in a solid off white cotton fabric which does have a few age spots in the fabric lining.
There is no size inside, just the original "Beach Mates" label. Probably fits a modern small to small medium.
The top when measured flat is 16 across or about a 32" bust.
The bottom un-stretched is about 12" when measured flat, so up to about 34" waist when stretched out.
Total top strap length of each strap is about 16" which adjust in back to size with a button loop.
