Very cool 2 piece prarie costume. I believe it was made in the 1970s-80s as an authentic costume for something, because the closures are hook and eye, button (no zippers).  At first, I thought it might be an antique, and it is not. Technically, it is vintage.  Kind of a teal, bright blue floral print fabric. The top has a darling, delicate lace collar.

Great condition! No labels or sizes, as I suspect it was handmade. Please check measurements.
