- 4-way stretch knit fabric with at least a 50% stretch but no more than 75% stretch- Recommend a blend of at least 5% spandex/lycra for good recovery. Avoid lightweight spandex/lycra and loose knits (they tend to stretch and sag and do not have a good recovery). Avoid also 2-way stretch widthwise knits.
- Optional: Clear elastic to stabilize the waistline.
- Optional: 3/8” strips of four-way stretch interfacing to stabilize the facing neckline.
