How to shorten a lined jacket?

To shorten a lined jacket, first, measure how much you want to reduce the length and mark it with tailor's chalk. Carefully remove the lining from the hem by unpicking the stitches, then cut the outer fabric to the desired length, allowing for a hem allowance. Fold the raw edge under, pin it in place, and sew it securely, then reattach or trim the lining to match the new hem. Finally, press the hem for a polished finish.
