I love a mock neck and love wazzie wool, so I could not resist trying this. I also could not decide between the black with white birds, or the white with black birds. I ordered both in my usual size small. I am generally cold and I pronounce this a perfect top for wearing under a jean jacket in low seventies temps (my house temp in the winter). I will keep both tops, but because I am picky I have a few tweaks I would suggest for improvements. I am about 5' 5" 126 lbs and would have liked an extra inch or two in length for it to either hit at my hipbones or stay tucked in. I also wish the bird print was lined up better where the seams are (there are partial birds by both of the front shoulder seams). Lastly, the white background actually looks gray instead of white. I do really like the tops and believe I will wear these often. I hope there will be a long sleeve option next winter that is more of an ivory background with black birds and does not chop up the poor birds images at the seams. Also hoping to see some summer-weight wazzie wool options again this year. Please make my day Oiselle and offer a thin summer wazzie wool cap sleeve t-shirt and racerback tank in black and dark heather gray options.
