How to Crochet a Bra. Crochet lingerie can be very sexy. If you would like to try to crochet some yourself, start with something simple, like a bra. A bra can be very simple to crochet. You'll just need to take some measurements and follow the pattern. Here's how you can make yourself a halter bra.
Take Some Measurements
Measure around your rib cage. Start by placing the end of the measuring tape in the middle of your chest. Run the measuring tape below each breast and around your back. Write down this measurement.

Take a measurement of the width of your breast you want your bra to cover. Do this by taking a measurement across your breast. Make sure the tape is touching your body exactly where you would want the widest part of the bra to touch.
Hold the edge of the tape at the top of your breast, and measure to the point under your breast where you held the tape in Step 1.
Get an over-the-shoulder measurement. Start with the tape on your back, where you should like the band to hit. Throw the rest of the measuring tape over your shoulder, and measure to the place beneath the breast where you took your first measurement in Step 1.
Check your gauge. Chain at least 30 stitches, and single crochet each row thereafter until the piece measures four inches. Measure how many rows are needed per inch. Measure how many stitches are needed per inch.
Crochet the Cups
Chain the necessary number of stitches to get the length you calculated in Section 1, Step 2. Then single crochet the next row, without decreasing. This will be the bottom of one of the cups of your bra.
Continue single crocheting until your piece measures half the length you measured in Section 1, Step 3.
Start decreasing your stitches. You will want to have one-third the number of stitches that are in your rows now. Determine how many stitches you will need to decrease by, by multiplying the number in your row now by two-thirds. Count how many rows you needed in Step 2. Divide the number of stitches you'll need to decrease by the number of rows. This is how many stitches you will need to decrease per row.
Keep decreasing until your piece measures the total length you calculated in Section 1, Step 3.
Stop decreasing your rows, and continue to single crochet across the rows. Continue until your entire piece measures the same as in Section 1, Step 4.
Repeat this process for the other cup of your bra.
Make the Band and Finish
Make a chain that will give you the length you measured in Section 1, Step 1. Single crochet the next row.
Move off the row. After you use single crochet to the end of the first row, chain enough for one inch. Then chain the same amount you used in Section 3, Step 1. Then chain enough for 1 inch. Use a slip stitch to join this new chain to the opposite end of the chain you started in the first step.
Chain one inch. Use a slip stitch to join this chain with the one you started in Step 2 of this section. Single crochet along this long chain. Stop one inch from the end. Chain enough for one inch, and use a slip stitch to join the short chain with the original.
Thread the elastic through the two short ends. Trim the elastic so that it is the same length as the long chain.
Sew hook and eye claps on the edges of the elastic.
Use a needle and thread to sew the short ends of the crochet chain to the elastic. Now you've completed the band of your bra.
Finish by sewing the cups of your bra onto the band.
You can leave your band with the elastic exposed, or you can use a tapestry needle and some extra yarn to make zigzag patterns between the top and bottom edges.
