In the lingerie sew-along I orgnized a few years ago I’ve published this post on how I sew the elastic to the band. I’m re-posting it here for general information. I’ll try to gather a bit of those posts as a conclusion to my lingerie sewing month.
One of the most common problems in bra making is the rolling/flipping of the elastic to the inside. This is often caused because the elastic is sewn too low on the band. In one of the classes I took it was told that the maximum height of the band under the cup is 1.25 cm (0,5 inch). It was said that in a lingerie sewing contest this was one of the things that got extra attention.
This is the way in which I sew the underband. It’s specially made as a tutorial, so only a partial bra is shown and non-matching colors are used for all parts.
