Vintage Embroidered Blouse

1970s cotton collared blouse with beautiful floral embroidery on chest and shoulders. Purchased from another seller but unfortunately too big for me (I typically wear xsmall/small). In very good vintage condition - does have some light marking at left pit as shown and light piling. No tags or size listed, please see measurements. Measurements 15” shoulder to shoulder 20.5” pit to pit 23” length
