This will be a quickie, since you've seen both of these patterns before.
Butterick 4222, which is sadly now OOP. I've made them many times and very much like the pattern. The pants are Simplicity 2290. I've made them before here.
Thomas. The middle, red one is James and the bottom, grey one that Logan is pointing to is Spencer. You can also see inside the collar in this picture. I decided to break from tradition and try the bias bound collar on this top. Naturally, despite having just written about this method, I managed to flub it up. I ended up with the bias tape on the outside, rather than tucked into the facings. It works fine, it just isn't as pretty. Anyway, the method was definitely less fussy and I think I'll be using it for PJs from here on out. The handstitched method is pretty and I'll reserve it for blouses and such where I don't want any external stitching.
