I used McCall 6559 for this, but I wanted to be able to wrap it at waist level. Version A was too short and version B would wrap at your hips, which seemed less flattering and not at all practical for practicing yoga. So I used version B and shortened it above the ties by about 10 cm. Now I can wear it at the waist as well as up high.
Getting fancy: as a bow:)
I can leave it open. The ties don't get in the way too much.
This is how I will wear it most: wrapped at the waist. I can either knot it at the back or just tuck the ties, which would be more comfortable for yoga.
I'll be making more as this is really a garment I need and will use. The tank dress is an old fave: Simplicity 2865, a Built by Wendy pattern. I made it several years ago to wear to class over my yoga gear. As you can see, my yoga capsule is an ongoing project! Do you sew for specific activities?
