Okay a tip from a lazy sewist/quilter. I go look in the clearance section of RTW (ready-to-wear) stores, buy an item that fits me well, take it home and take it apart. Then I make a pattern from it (using freezer paper, which I prefer because I can iron the pattern pieces to my chosen fabric and cut it out, instead of pinning. See - I told you I was lazy! 😆 )
I once bought an Eddie Bauer blouse on clearance for $4 and have made probably 10-12 blouses with that as my pattern. Since it already fits me, I don't bother with making a muslin. And I can change small things such as the length of the sleeves, the hemline, the collar, etc.
