These tops can be hard to date because they were popular for multiple decades (and this one is home sewn), but based on the fabric/print, I suspect this top dates to the 1970s. The fabric is a substantial weight cotton and has a small floral print on an ivory background. The neckline and sleeves have ruffles with rickrack trim.
Size: small to medium
Bust: 40" (wearer's bust should not be at max--probably best for 34-37" bust)
Condition: Very good. The sleeves appear to have elastic that is stretched out, but the top looks cute with the sleeves as they are!
