I recently finally got a sewing machine. I wanted to try my hand at bra making but haven’t found any bra supply stores that ? sell underwires that would be close to bra size I currently wear. After reading that Gossard ultimate strapless bra has a plastic underwire. I kind of wonder if a 3d printed underwire give the support that I need. There is a fab lab near by so I could test it out but I would feel odd of I just showed up and asked.
