Materials Needed
To make a tankini top from a bra, you’ll need the following materials:
1. A bra
Choose a bra that fits well and has a sturdy construction, as it will form the base of your tankini top.
2. Fabric
You’ll need stretchy fabric that matches the color and texture of your bra. Look for fabric that is suitable for swimwear.
3. Elastic
You’ll need elastic to make the straps and secure the edges of the fabric.
4. Sewing kit
A basic sewing kit that includes scissors, pins, and a sewing machine or needle and thread.
5. Measuring tape
You’ll need a measuring tape to ensure that your tankini top fits properly.
Tips for Selecting the Right Type of Bra for This Project
Here are some tips to keep in mind when selecting a bra:
- Look for a bra that fits well and is comfortable to wear. You want to make sure that the bra will also be comfortable to wear as a tankini top.
- Choose a bra that has a smooth, seamless finish. This will make it easier to sew the fabric onto the bottom of the bra and create a clean, finished look.
- Consider the shape of the bra. A bra with a straight across band will be easier to work with than one with a curved or angled band.
- Look for a bra with a supportive band. This will help the tankini top stay in place and provide the necessary support.
- Think about the style of the bra. A bra with a plunging neckline may not work well for this project, as it may not provide enough coverage for a tankini top.
- Check the material of the bra. Some materials, such as lace or mesh, may be more difficult to work with when attaching fabric to the bottom.
Steps to Make a Tankini Top From a Bra

Here are some step-by-step instructions to get you started:
Step 1: Choose a bra that fits well
Choose a bra that fits well and has a smooth cup shape. The bra cups will form the base of your tankini top. Make sure the bra is clean and in good condition.
Step 2: Trace around the outline of the cups and the band
Lay the bra flat on a piece of paper and trace around the outline of the cups and the band. This will give you a template to use when cutting the swimsuit fabric.
Step 3: Cut the straps off the bra
Cut the straps off the bra, leaving the cups and the band intact. Use scissors to cut as close to the cup and band as possible, without damaging the bra.
Step 4: Cut out the swimsuit fabric
Cut a piece of swimsuit fabric that is long enough to wrap around the bra and cover the cups, with extra length to make straps. The fabric should be stretchy and appropriate for swimwear. Lay the fabric flat and place the bra template on top of it. Trace around the template with a fabric pen or chalk, and then cut out the fabric pieces.
Step 5: Pin the fabric around the bra cups
Pin the fabric around the bra cups, making sure it is evenly distributed and there are no wrinkles or gaps. Start by pinning the top edge of the fabric to the top edge of the bra cups. Then, stretch the fabric around the sides and bottom of the cups, and pin it in place. Smooth out any wrinkles or folds in the fabric as you go.
Step 6: Pin the ends of the fabric
Pin the ends of the fabric at the back of the bra band. Make sure the fabric is snug against the band, but not so tight that it pulls or distorts the cups.
Step 7: Sew the fabric onto the bra cups
Using a sewing machine or needle and thread, sew the fabric onto the bra cups, making sure to stitch through both the fabric and the bra to secure them together. Start by sewing the top edge of the fabric to the top edge of the cups. Then, sew around the sides and bottom of the cups, being careful not to sew through the bra straps or the band. Trim any excess fabric.
Step 8: Cut swimsuit fabric to make the straps
Cut two long strips of swimsuit fabric to make the straps. The length of the straps will depend on how you want to wear your tankini top (halter, racerback, etc.). Make sure the straps are wide enough to be comfortable and provide adequate support. A good rule of thumb is to make the straps about 2 inches wide.
Step 9: Sew the straps onto the band
Pin the straps to the back of the bra band, making sure they are evenly spaced and aligned. The straps should be angled slightly towards the center of the bra, to provide better support. Sew the straps onto the band securely, using a zigzag stitch or other stretchy stitches.
Step 10: Try on the tankini top
Try on your new tankini top and adjust the straps as necessary for a comfortable fit. If the top feels too loose or too tight, you can adjust the straps or take in the fabric at the sides of the cups. If the straps feel uncomfortable, you can add padding or a soft lining to the bra cups.
Step 11: Add embellishments
If desired, add embellishments such as beads, sequins, or appliques to personalize your tankini top. You can also experiment with different fabrics and colors to create a unique look.
4 Ideas for Customizing the Tankini Top
Customizing a tankini top can be a fun and creative way to make it uniquely yours. Here are a few ideas for adding your own personal touch:
1. Embellishments
Add some sparkle and shine to your tankini top by embellishing it with beads, sequins, or rhinestones. You can use fabric glue to attach them or sew them on for added durability. You could also add some fringe, tassels, or other decorative trim for a fun boho vibe.
2. Different Fabrics
Mix and match fabrics to create a one-of-a-kind tankini top. You could use a contrasting fabric for the straps, or add some lace or mesh panels for a touch of elegance. You could also experiment with different textures, such as velvet or satin, to create a unique look.
3. Custom Printing
If you’re feeling really adventurous, you could try custom printing your own fabric to use for your tankini top. There are many online services that allow you to upload your own designs and have them printed on fabric. This way, you can create a truly personalized and unique look.
4. Applique
Another way to add some interest to your tankini top is by adding applique. You could cut out shapes or designs from different fabrics and sew them onto your top for a pop of color and texture.
