Oh my, yes.
A few months ago, I was shopping on Amazon. I have found some nice boots, jeans, and such and wanted some nice sweaters. I find these adorable things and I can't resist. The price was right, so I bought three: one each of pink, brown, and black.
They arrived with each one wrapped in cellophane that was covered in Chinese writing. I take the first one out and I don't even have to try it on. Small is an understatement. I checked the tag. I ordered XL and the tag confirmed it is XL. I think the Chinese Translation is "Extra Little"! I have a neighbor with a 9-year-old daughter, so I gave them to her. They fit perfectly! And they still look adorable on her.
I have learned that I really have to carefully check the actual size chart, convert cm to inches, and then puzzle over how XXL means a 40" bust. What? I'm 46" and don't qualify for XXL.
