I have been talking a lot about my struggles and successes with fit. This has been my free online tool, found here. I know it looks a little juvenile, and I actually used something like this during my 4-H years. This is provided by the University of Florida’s library and they have a number of these type of publications (again many I read and used during my formative sewing years) for free. They are now online! Hurray! I have referred to their old school diagrams when needing to identify fit issues and I love their straight forward approach. I also like that they include multiple versions of how to alter something: regular or kimono? with or without waist seam? no problem! Its covered. It is not fancy or modern, but it works! I highly recommend it!
