Tired of finishing sewing your bra only to find that it doesn't fit because you trying new pattern or because you've changed enough that the bra cup is to big or is a little to tight?
Then this test band kit is a good start to avoid sewing up a new bra for every cup correction you need.
This kit contains materials to allow you to sew a test band in the band size you need and then use the test band to sew in your cups before they become part of your bra.
