Daisey Textured Sheer Lace Top

I don't think I am the only one who has noticed that sizes are becoming smaller. I used to be an x-small always, and I've actually stayed the same weight and measurements in the past few years. I bought a small, because I assumed that was probably the size on the model. Looks comfortable, not overly loose, not overly tight. When I tried this on though, it was tighter than I had anticipated. It isn't that it doesn't fit. It does. It simply isn't the fit that I was expecting based on the online photos. It looked much more awkward. I wanted the slight drape, the casualness. I will likely still wear this layered with other pieces, but I don't like how it looks enough to wear as a standalone piece, as I had planned. Didn't a size small once represent size 4-6? This fits like a 0-2.
