Dear Noval,

Methinks you're putting the cart before the horse. One doesn't begin
with a dress pattern, then go back and try to put support in it. I
taught design for years, and students were never allowed to cut into
their good fabric until they had worked out all the bugs in a toile.

If you're taking courses in fashion design, you should have dress
forms in the studio. Find one similar in shape to you (or your
model). Put a bra on it and stuff it, if necessary, to give it the
desired shape. Then build a support garment right on the form with
net, including boning where required. The boning can go on the
outside of the net, because this will be the interlining, with your
fashion fabric on the outside, and the lining on the inside. Wherever
the dress is going to open, the support needs to open in the same
place, so allow for seams.

If you're a beginner and this is beyond your capabilities, purchase a
foundation that can be attached to the dress. Put it on the dress
form, and build the dress over it. The facings of the dress may be
turned and sewn over the foundation to hold it in place.
