Vintage crochet crop/bra top, halter neck and double tie in back. I wore this 27 years ago (!) on my honeymoon in Jamaica. Tag has been cut out but I'd estimate a size XS/S. I was a 34A and wore without a bra. I think it would easily be fine for a B cup too. Maybe a small C cup, depending on your comfort level with less coverage. Ties in back make it adjustable for different body types. Buttery yellow color.
