I recently had a new piece of knitwear taken it at the waist. I took it to my alterations lady, who overlocked the side seams and re-steamed the garment for $10. I’m impressed with the results. It’s made a huge difference to the fit of the garment, making it less boxy and more streamlined. After the alteration it looks good both as is and belted at the waist.
Knitwear can be successfully altered at the side seams by a competent seamstress. In fact, I’ve never tried this, but you’ll probably be able to narrow the width of knitwear sleeves in the same way. This got me thinking. Are there ways to shorten the sleeve and hem lengths of knitwear? I’ve always thought that this can’t be done, but now I’m not so sure.
