This was a gift from my son. So, with that I guessed my size. My rating is Excellent. I reached out to the seller and no problem I able to exchange for size up 2 times. So I didn't read the sizing which it described in detail for the sleeves etc. I was able to exchange it a second time, I was able to get a support person on the phone the second time and then follow through was immediate. The women's flannel is beautiful, the sleeve size is the same for women's XL and XXL. So, if you wear a looser fit size up from there. Think large comfy shirt over leggings with boots. Excellent! Thank you Pladra!
