When she was two, I made her a size 2. This time, I made a size 6. She is only four and a half, but I wanted it to fit next year, and now I know this jacket runs small. (It is meant to be fitted.)
I also added a little "L" stamp in fabric ink (on some blue polka dot bias tape) in order to patch a small hole I made in the binding while trimming threads... whoops! Luckily she especially loves the "secret L."
I wouldn't rate this unlined velveteen as suitable for 25° and light snow, but it was okay for a quick photoshoot. She's also wearing pink handwarmers that my mom knit for her. :)
I highly recommend reading Anna Maria's suggestions for sewing and caring for her velveteen. I was careful to iron on the wrong side of the fabric whenever possible, and to lift straight up whenever pressing the right side. Sliding the iron can definitely leave marks.
p.s. skirt as top made a lovely version of this in another AMH velveteen a while ago...
