A sports bra is a type of undergarment that is designed to support a woman’s breasts during physical activity. The main purpose of a sports bra is to reduce breast movement, which can lead to discomfort and even pain. Wearing a poorly fitting or insufficiently supportive sports bra can also contribute to breast pain. Many women choose to wear a sports bra during activities such as running, aerobics, and other high-impact activities.

There are many different types of sports bras on the market, and the right one for you will depend on your breast size, activity level, and personal preferences. In general, though, there are three main types of sports bras: compression bras, encapsulation bras, and combination bras. Compression bras are designed to compress your breasts against your chest wall, which helps to reduce breast movement. Encapsulation bras have cups that support each breast individually, much like a regular bra. Combination bras offer both compression and encapsulation.

Choosing the right sports bra is important for both comfort and injury prevention. If you are engaged in high-impact activities such as running or playing tennis, you will need a more supportive bra than if you are doing low-impact activities such as walking or yoga. It is also important to choose a sports bra that fits well; too tight and you may experience discomfort, too loose and it will not provide adequate support. You may need to try on several different styles and sizes before you find the perfect fit.

What You’ll Need

-A pair of men’s boxer briefs
-A needle and thread

1. Cut the legs off of the boxer briefs. You will now just have the waistband and a rectangle of fabric.
2. Fold the fabric in half lengthwise, so that the waistband is on one side and the two raw edges are on the other.
3. Sew along the raw edges, leaving about a 1/2 inch seam allowance. Be sure to backstitch at the beginning and end of your stitching.
4. Trim any excess thread and turn your make-shift sports bra right side out. Voila!

Step One: Cut the Underwear

Start by cutting off the legs of the underwear. You will want to leave about an inch or two of material above the waistband. Next, cut a slit up the center of the back of the underwear so that you can put it on like a tank top. Be sure not to cut too close to the waistband or else the underwear will not stay up.

Now that you have your basic sports bra shape, it is time to add some straps. Cut two strips of fabric from the legs of the underwear that are about an inch wide and long enough to go around your back and over your shoulders. Attach these straps to the back of the sports bra using a sewing machine or needle and thread.

Step Two: Sew the Sides

With the shorts turned inside out, pin the two side seams together. Start at the bottom of the short and work your way up. I like to sew with a 1/4″ seam allowance, but you can do whatever you’re comfortable with. Just make sure it’s consistent throughout. Sew the two side seams together with a straight stitch.

Step Three: Sew the Top

Now that you have your fabric cut out, it’s time to start sewing. Begin by folding the long edge of one of the fabrics over 1/4 inch and press flat. Then fold it over another 1/4 inch and press again. Sew along this edge close to the folded edge. Repeat this process with the other piece of fabric.

Step Four: Try It On

Now try on your new sports bra! If it feels too tight, you can adjust the straps or add more elastic. If it’s too loose, you can remove some of the fabric in the back or take in the side seams. Once you get a good fit, sew around the edges with a zigzag stitch to finish it off.


In conclusion, making a sports bra from men’s underwear is a relatively easy process that can be done at home with just a few materials. The finished product will provide adequate support for low-impact activities, such as walking or light jogging. For more intense activities, such as running or playing sports, you may want to consider investing in a more heavy-duty sports bra.
