Most of my drafting for stretch is based on a simple tee shirt pattern which could be obtained either by using a commercial pattern which you know fits well, or by copying a t-shirt.
Copying a T-Shirt
Copying a T-Shirt Part 1 - How to copy an existing shirt.
Copying a T-Shirt Part 2 - Tweaking the fit. It looks so much better!
If that seems a bit daunting, you can try Copying Clothing by Taking it Apart.
Darted Tank Top - A more flattering tank style, particularly for a fuller bust. This pattern forms the foundation for a lot of other stuff too. It is an adaptation from the t-shirt pattern.
Drafting the Tank Top
This is a 3 part series for making this design from a basic t-shirt pattern (you don't even need to make a new pattern piece).
This is my version of the Drapey Top from the Great British Sewing Bee, click here for a diagram and explanation of how the drafting works.
Basic Skirt - I never did finish this skirt band tutorial! Useful for turning stretch shirt patterns into dress patterns.
Basic Skirt Part 1
Tank Dress - This is the foundation for most of my stretch dress patterns. It is built with the darted tank top and the basic skirt. You could do it with just the Tank Top.
