I got this jacket today & am in love with it. I have to say though, I ordered the size I would normally wear & it does fit, but it is definitely not "roomy". I like the slim fit & it is not uncomfortable, it is comfy. I love the lining inside, which helps it slide on over a sweater, or long sleeve. It s definitely lighweight, which is what I wanted. The length is perfect! If you are closer to the next size, or like a baggier coat, I would suggest ordering the next size up, but if you are good with a slim fit that is still cozy, order true to size. Buying clothes online can be scary, but I am super glad I bought this!Will be wearing this often!
