Bramaggeddon (aka Building a better bra)

[LMAshton]

What you *could* do is find a bra that has cups that fit you perfectly, even though the bad will be too large, and disassemble that for your cups pattern. Then use your existing bra with the band that fits perfectly, disassemble, and use the perfectly fitting parts as templates for a bra pattern.

That's a good idea.
