Bra inserts can create a fuller bust, push up cleavage and keep your breasts in place. Sewn into dresses, bathing suits, bras and tops, the inserts allow for extra support without the discomfort or hassle of wearing a standard bra. They're also a great bra substitute when you're wearing tops or dresses that feature low-cut backs or strapless designs.
Choose a pair of bra pads that are close in color to the piece of clothing you'll be sewing them into. For dark colors, go with black; for lighter colors, select white or beige. Also decide on the shape of the bra inserts and how much padding you'll require.
Make sure the fabric of the clothing is thick enough to support bra inserts. Ideally, the fabric should be lined, so that the stitching will not show on the outside. This will also ensure a strong foundation for securing the bra pads.
Pin the bra inserts into the article of clothing. Be sure to position them correctly based on their shape: Some bra inserts are rounded, while others are more triangular. Pin from the outer part of the garment so that you can try it on to ensure correct placement before permanently sewing in the bra pads.
Using matching thread, sew around each pad, employing an overhand stitch. Begin on the inside of the clothing; push the needle through the bra insert and into the first layer of fabric (or just catch a few of the fabric's threads), making sure you cannot see the stitches on the outer part of the garment. Bring the needle and thread back to the pad and push through again, and then into the fabric. Continue around the entire pad, spacing the stitches about 1/4" apart.
Make a few knots at the end of the thread and cut past the knotted part to keep the stitching from unraveling. Your bra inserts are now permanently secured.
