Hmmm... The apron I could definitely do, but for the jumper-thing, I wouldn't be able to do the top. I'm still learning how to do fitted tops that actually fit right, but if you're willing to have the jumper be two pieces (a separate top and bottom) then I can make the bottoms, since they look just like bloomers.
But yeah the apron I could totally do, I'll just need slightly more specific measurements than a normal apron.
