Close the opening in the sleeve lining with a neat machine stitch or by hand.
Turn the garment right side out and carefully shape all edges and corners, ensuring the front edges, collar, and vent are fully turned and properly aligned.
Press the garment thoroughly:
Roll the seams slightly toward the underside where appropriate to prevent them from being visible on the right side.
Ensure the lining is distributed evenly inside the garment and does not pull or distort the outer fabric.
Optionally, secure the lining with thread tacks at the armholes and side seams to prevent shifting during wear.
Verify that all edges are clean, sharp, and symmetrical.
Ensure the hem hangs evenly and the garment maintains a balanced silhouette.
Give the garment a final press, ensuring a crisp, tailored appearance.
