I’m new here, so thank you in advance of any help you can offer.I bought this back in 75 or 76 in a boutique in South Wales, UK. I wore it a few times to “posh” events. The cross straps fit under the bust, through the side seams and are partly elasticated, coming together at your back where a bra closing would be. There are small covered buttons at the wrist, the arm seams are open up to within a few inches of the shoulders. It is comfortable to wear, the fabric feels beautifully soft and silky. My question is, why can’t I find anything even remotely like it anywhere I’ve looked, or am I just looking in the wrong places?!
