Sheer, summery empire waist dress purchased in Rome, Italy

During our autumn trip to Italy in 2023, it was much hotter than expected. I purchased a few light dresses in Rome and didn't get around to wearing this one. It's sheer and light as a feather, 40" (101.6 cm) long and 23" (58.42 cm) across at the top seam and 47" (119.38 cm) across at the bottom. There is no material label inside. I'll guess it's a linen blend because of the feel. Any other questions, please ask. I purchased it on sale so it's a great value!
