Surprise synthetic material
"I bought the dress never thinking to check the material composition. I assumed flannel meant cotton or wool flannel, like it usually does, especially for a quality brand like US. Wore it today and was immediately sweaty - it's polyester and rayon and you can feel it. Two stars because it is at least a nice weight. But I'm so disappointed to find this such a worse quality material than LL Bean etc. I love US but this was a let-down."
