Just received this today and I love it! I'm 5'5" and slender and the XS fits just perfectly. Last year I bought a similar item from another company and I can already tell that this fabric is softer and nicer. I haven't bought from LLB in years but products like this will keep me coming back!
I purchased this in the same size I would normally get the 1/4 zip fitness fleece (med. misses) and it was way too big for me in the belly area. I gave it to a relative instead of returning it because it is a nice, soft, thin (but warm) zip hoodie. If I were to re-order, I'd order a size down.
Love this fleece hoodie! It is lightweight yet warm. The quality is good, the colors don't fade and the design is modern! Also, very easy to layer a down vest over.
