Here is a sketch of the bra I will be teaching you to sew. What I really recommend you, is to follow this step exactly when making your bra.
First of all, decide what is your bra main fabric. My entire bra will be made from this stretch beige lace.
But we need other materials as well. Every part of the bra must obey some rules. Let’s look at the bra parts. Not, let’s see each part what materials require.
This means we will use this pattern piece (which has already seam allowances):
For my lining I use some magic fabric I found to be great. It’s actually cotton interfacing. When pressed with an iron, it will glue to my lace:
As for the pattern piece, the cradle with seam allowance will be used twice, once on the main fabric, second on the lining:
For the top layer – lace – I use the pattern pieces that have seam allowances on all sides. For foam and for lining, I use other pieces (please note that seam allowance was removed from some sides).
The lining I use is the same as the one I use for the cradle. The foam is this fabric I found in one shop and is called neoprene.
For straps, I am going to use these metallic pieces (strap sliders). I don’t have metal rings and I don’t want to put the plastic ones. The above pieces will work for my purpose. If you have a pair of rings, replace them with a pair of strap sliders.
And embellishments – lace for cups, a flower for the center. I gather all these in one bag. When sewing the bra, I look for supplies in that bag only. When pausing from sewing the bra, I put everything back in the bag.
