Vintage Madras Short Set

Not sure if this is vintage, but I am 72 and we used to wear madras in the early 1960s all the time. Sleeveless blouse, 100% cotton says it is a size 18 but it’s more like a large I’m not sure if 18 is the size. Pit measures 20 1/2“ by 23 inches long. Shorts are lined a little over 15 inches wide inseam of 4 inches. Where this cute plaid top with jeans or jeans shorts or make it an outfit with the matching shorts. Definitely a vintage vibe.
