THIS POST using a second sweater to make it longer**
I'll keep this short because I've done similar refashions before and this one isn't much different.
What separates this one from the others is that I looked for the longest, biggest men's sweater I could find so that it would fit more like a sweater dress and not as slouchy. I left the sleeves alone because super long, comfy sleeves are irresistible to me. I can give you directions for shortening your sleeves, though. Or maybe I'll just bite the bullet and shorten the sleeves on this one. I love long sleeves.
(1) Get it. Start with an over sized sweater. Way over sized. I think this was either an XL or XXL men's sweater from Goodwill. If you found an over sized sweater dress at Goodwill, that would work too- and it would be longer!!
