To make things easy I set the sleeves before sewing the side seams.
It is my practice to pin up to the gathers on both sides and then pull the gathering threads,
even the gathers and pin.I do all four sleeves.

Sew in the sleeves and check them then sew the side seams and sleeve seams all in one seam.

With the jacket and lining inside out, roll up the sleeves and pin them.
Then pin the two pieces right sides together aligning all the edges and encasing the collar and skirts.

Sew around the edges leaving an opening at the back neck of about 6".

Trim the edges and the corners, unroll the sleeves and turn right side out through the neck opening.
