Hello! I have this velvet dress with a side metal zip, and I'm stumped about dating it. It has tulip sleeves, no shoulder pads, and no other closures save the side metal zip. The seams largely appear to be pinked. I've searched patterns and images for tulip-sleeved 40s/50s long dresses and can't find many, especially not with this neckline. Could it be more modern? Thank you in advance for any help you can provide!
