This pattern is made out of cut-and-sew foam and it has underwires. It comes in sizes 70B – 95C. I made the size 75A which fit nicely for me. The three-part cup can be used to add pretty decorative fabrics to a part of the cup. I chose to use some pretty corded lace that I had had lying around.
I had to do some modifications. First, I did not need the thick, padded straps. I narrowed down the strap fastening point in the side cup piece and decided to make the whole strap out of the strap elastic. Then there is the fact that I cannot wear normal underwires. Those press painfully against my sternum. If you suffer from the same problem or just want to make your bra into a more plunge type bra, you can find some tips here on my blog.
