So as part of a costume I’m building, I have to tailor in a boiler suit to be a little less loose, and then add some sleeves to it to make it full length on my arms. Only problem, I have no idea how to do that, so I was wondering if there was anybody floating around amongst the textiles experts who might be able to lend a hand?
I’m doing a similar thing with legging, reducing down one size. What I did was cut off all the seams then used the overlocker to sew it back together. For the sleeve you could unpick them rather than cut off the seam allowance and use that as your template to create a new sleeve.
Basically take the boiler suit apart at the seams and sew it back up.
