Field Trip Raglan T-Shirt pattern. I added about 12" to the length. I also added 2" of width at the bottom of each side seam, then connected that point to the corner of the arm opening side seam to get a simple A line dress. Of course, the thumbhole sleeves were part of the research for the last post (how to make thumbhole sleeves). This is the size 5. L can wear a 4, but I wanted some room to grow, and there's plenty.
This crazy big print is some sort of cotton blend knit from my mother in law's stash. I think it's a print you either love or hate, and I'm not sure which side I'm on. I've been saving it for long enough that I must at least like it. There is certainly no chance it will go unnoticed. The arms and neck band are charcoal heather jersey knit. I wish I could remember where I bought it, I would get a whole lot more. Its got a subtle haylo of soft fuz that makes it extra snuggly.
