Butterick 3344, and the skirt is a half circle wrap, refashioned from Butterick 4790. I've worn it before (on Day 4), but I definitely prefer it with this top!
New Look 6638 and Logan is wearing both top and bottom from New Look 6641, which I have used a half dozen times at least! Myra doesn't always wear me made PJs as she has quite a few hand me downs from Logan, but all of Logan's are made by me! Mostly from this pattern and Butterick 4222, which I have also made easily a half dozen times.
