I try to avoid most alterations, they can become more than you bargained for – see Mrs Mole’s blog if you need to understand why! But sometimes I will repay a favour to a friend, which is how this came my way.
I needed to shorten a child’s suit jacket sleeve (image below). It has three buttons and buttonholes, and was needed quickly.
But rather than mess with those buttons and hem corners, I took off the sleeves, and cut the extra length from the top.
I traced the new seamline with thread and checked the fit and new length. Then it was just a quick trim before fitting it back into the armhole.
This could also be done with a mans suit , depending on how much needs to be shortened. Look out for a very tapered sleeve as if you move down too far you might not have enough width to fill the armhole! Always a good idea to thread trace and check fit first 🙂
