French ruffled shirt

This is from 2005, and I bought it in Montpellier, France. It's a beige button down with ruffle details and a longer hemline in front. Slightly sheer. It's marked a size 1, which their size guide says is an EU 38, but is more like an xs. Measures 17 in pit to pit, 29 in long in front, 26 in long in back. I wore it a handful of times in grad school over a cami, but have kept it for sentimental reasons, as that was my last trip to France. Super unique!
