This thing is fantastic. The collar reminds me of the 70s and the sleeves remind me of the 60s. There are no tags but the lot tag with a half size. The seams are unfinished. Thanks for your help!
I agree with Marian. This is part of a 1960s ensemble outfit. The dress would have most likely been a simple sheath style with perhaps just the bodice of the dress being the same lace and the bottom being a solid rayon or silk.
I agree with the 1960s dating. While it is not a true Cluny lace, it was made to imitate that style of lace. Very pretty color for spring.
