I successfully completed a wearable top for myself!! I think it is a good fit for the super stretchy Malden Mills/Polartec fleece. I have another planned with sweatshirt fleece but I think I will go up a size in that one so I can layer more under it. The fleece one I can only put a thin tank top under but it's super warm so that's okay. I think this size will be good for a lighter knit fabric as well but I still might alter the sleeve and at the wait to give me a bit more room.
Overall I'm very pleased with the outcome and the hubby is very impressed!
