3/4 英吋針織鬆緊帶，白色，3 碼

The curl resistance is a lifesaver for sewing curved necklines—it stays flat and cooperates without twisting. And it kept its width under a firm stretch, which made the waistband on my daughter's leggings sit comfortably.

Sewing a swimsuit cover-up took way less fiddling than I expected — this elastic stays flat when you stretch it, no curling or twisting. The white knit is soft against the skin, which makes a real difference for a neckline.

Used this for the waistband on a pair of lounge pants and it stayed perfectly flat, no curling even after washing. It stretches without narrowing, which made sewing it in way easier than the cheap stuff I've used before.
