I usually wear a PM/PL. I ordered this in turquoise and the color was beautiful. However, the fit was not. It might just be that because I am 5'2" tall, this style is too long for me. But I did order a PL, and still, it was tight around the back while the sleeves were too long. I think a PXL would completely swamp me. The fleece was very soft but also very "thin" compared to other fleece sweaters I own. The price was right because it was on sale, but I knew I would never wear it. So, I returned it. I do like Nordstrom's return policy and the ease of mailing back online orders.
I thought this was just ok. It's very comfortable, but big and boxy, and I couldn't seem to get it to lay right. The quality of the fabric is also a little less than I expected.
This cardigan is very good quality. it is thicker and warmer than I imagined. The fit is good, looks great with skinny jeans and boots. I may be trying more colors!
