Bra to be copied (this needs to be a seamed cup moulded bras are pretty much impossible for the home sewer)
Suitably sized paper - A3 is usually large enough (computer print out paper, or dot & cross, or wall lining paper!)
Pencil & note paper
Tracing wheel, and carbon paper
Spray glue (like the stuff they stick pictures on the wall with) or Double sided tape
Only disassemble one half of the bra; keep the other side intact to examine if you get stuck.
Write detailed notes as you dismantel your bra and make lots of sketches, also start at the bottom of the page and work upwards so that your finished notes are in the correct order for making the bra . Remember to write the reverse of what you're doing when taking apart the bra (i.e., when detaching the straps, write instructions for how to attach the straps).
Examine the bra carefully to determine the steps in which it was assembled. You can tell which seam was sewn first by paying attention to where one seam crosses another. Use a marker pen drawing arrows on the bra for direction of stretch, numbering the cup pieces, and marking seams.
For each step, note the stitch type (straight, zigzag) and approximate length used. As you cut the threads holding the bra together, leave the thread ends in the fabric; this makes it easier to see the seam allowances used.
