FABRIC AND FIT
Fabric recommendations:
For the best results, choose knit fabrics with excellent recovery and a moderate amount of stretch—ideally at least 50% crosswise stretch with good snap-back. Cotton/spandex blends, rayon jerseys, modal knits, bamboo knits, and some rib knits all work beautifully. These fabrics offer enough structure to support the body-skimming silhouette while still remaining soft and comfortable for all-day wear.
If you want a more sculpted, supportive feel, look for fabrics with a firmer hand and higher stretch percentage. This combination of qualities helps maintain a sleek fit through the sleeves and torso and help the shelf bra feel secure and stable.
Lightweight jerseys will produce a softer, more relaxed silhouette, ideal for layering under sweaters and jackets.
Avoid fabrics that grow with wear, have minimal recovery, or are too lightweight to support the neckline and shelf bra. Slippery rayon jerseys can work, but make sure they have strong recovery.
Because Ione is designed to sit close to the body, choosing the right fabric is integral to achieving the polished, sculpted look the pattern is drafted for.
