I’m making the Starlet Suit Jacket on Craftsy (so excited to learn tailoring!) but I had to take the jacket in at the sides quite a bit (about an inch on either side). I’m worried that the armholes are too small but I’m not sure exactly how I should change them. It seems to me that I should just cut along the bottom on the armhole, making it deeper, so that the upper shoulder and sides of the armhole remain unchanged. (I hope that makes sense). Is that the proper way to fix things? How do I know how much to cut so that the sleeves still fit?
Thanks in advance for your help.
