Vintage silky cami unknown size

This is a vintage silky cami I’ve had for 20 years. It no longer has tags so I can’t be sure of the size or fabric content but it’s very smooth and silky. Doesn’t feel thin or cheap like polyester. I’m guessing it has at least some silk. Super flattering and forgiving fit due to being cut on the bias. I can wear it now and I’m a large but it’s slightly big in the armpits. It would fit a medium if you like it a little looser. It would definitely fit an XL and a smaller 1x, after that I’m not sure. Creamy background and a poppy red / red orange “smudged” floral pattern. Dots on facing, ribbon under buttons, and straps are a medium taupe brown. This is so gorgeous and I hate to let it go but I just don’t wear it anymore. Non smoking home with a non-stinky dog.
