I ordered this mostly because it appeared that it would be stylish yet sporty' something I could wear on casual dress days to work, yet still look classy. Although I found this to be the case, I was pleasantly surprised by how warm it was as well. I was sitting in my apartment on a chilly fall day, freezing because I would rather be cold than spend money to keep the place warm, and this baby arrived in the mail. I put it on and zipped it up and 20 minutes later I was sweating. How can something so thin and fitting be so warm? I absolutely love it! I am usually one to wear some nice jeans and a blouse out on a Friday night downtown, but the Friday I received this, I wore it instead and I received a ton of compliments, even though it was a more sporty outfit. It fits nicely and makes my mid-section look trim. I am also 5'11" and the length of the arms are perfect. I want another one NOW!
