Fett Flight suit help ?

[Mottrex]

Hi in the process of making a Flight Suit but getting stuck on the sleeves..
I've cut arms just above elbow and edged it then done the same for arms but my question is..
If I just re attatch it will gather up the flared upper arm..
What do people use if you go this method.

I was thinking placing just a few stitches to keep it it loose.

Any help would be appreciated.

First attempt was ok and just about held out for weekend. The inner sleeve did rip exposing my arm in photos grr but hey it's a learning curve.
That was back in October, I've since bought two more boiler suits for future projects and invested in a rather nice ESB flight suit complete with separate Flak, Neck, extra pockets and spats.
