I have two jumpsuits made from lightweight rayon challis fabric. They have very wide uneven oneseam legs. The outside legs are too long for me while the inseam is at a good place. I bought them at a booth during a rib festival a few years ago. I rather like them because they are lightweight and very comfortable but I never wear them because of the legs.
I don't want to shorten them because it will make the hems too thick and there is no way I'm cutting off this type of fabric because it's such a pain to work with due to the wiggle factor. After looking at many pants images I came up with the idea of making them "billow" legs like these
Blue Fish "billow" pants.
So now my dilemma is what to use for my "string" to tie them up. It needs to be easy to tie/untie without knotting and gentle washable (line dry). It needs to have the right weight. I'll sew it straight on the fabric (where a seam would be if there was one). I'll use matching thread so it's not easily veiwable.
I've considered thick yarn, shoe laces, flat sheer ribbon, string and twine. I've mostly dismissed them due to the fact it would knot too easily, not wear well or be too heavy/stiff.
Does anyone have suggestions on what might work? Or maybe I'm overthinking this.
