Usually, when I do a recon, it is to make a smaller shirt bigger. I can not figure out how to make the shirt looser. I have looked in the search box thingy and there isn't anything there. So, please, if you could be so kind to help me.
How big are the seams? If they're wide, you can take the seams out, then sew it up again with tiny seams.
Or add new panels with extra fabric.
