This blouse is very thin, possibly cotton with beautiful floral detailing and scalloped sleeves and neckline. Does anyone happen to know about how old this blouse is?
It is lovely. These blouse can be difficult to date from just a photo. It appears to be very similar to garments made in the The Phillipines or the Isle of Madiera. Filipino embroidered blouses have not changed much in style in the past 50 years or so, making it a bit more difficult to date. Probably fairly contemporary, 1970s at the oldest, is my guess.
Like Barbara, this reminds me of Phillipino tops and I don't expect it to be very old, '70s or '80s at the oldest. It has no bust shaping so best worn loosely.
these embroidered cropped length tops were also particularly prevalent in the 90s, often from Bali, too. however, the 90s are now vintage. so, there's that.
