Hi there,
Is the pictured wrinkling on the undersleeve a fact of life, or can it be adjusted? I wondered if it would work to pick up the undersleeve a bit or something.
I don't *think* it's a pitch problem, as the pitch looks ok otherwise.
Sorry it's a selfie!

I've taken in the seam on the double i.e. basted it further back from the edge. Is this 'cheating' i.e. will this have unintended, bad consequences? At first glance it looks kinda better...
(Left sleeve, foreground is mirrored while back is mirrored twice!)
And from the side:
