If you're looking to flatten your chest, rest assured you're not alone! There are numerous safe and user-friendly products available online for this purpose. However, if you prefer a DIY approach, you have a few options. For instance, you can transform a pair of compression shorts into a chest binder. When wearing a chest binder, it's crucial to ensure it's not too tight or made from unsuitable materials, as this could harm your tissues.
Steps
Turning Compression Shorts into a Chest Binder

Purchase or find a pair of compression shorts or shapewear. Any type of compression shorts will work for this purpose. If your chest and waist measurements are similar, you can buy your usual size. Otherwise, use a measuring tape to determine your chest size. Place one end at the front of your chest, wrap it around your back until it meets the starting point. Gently pull the tape to snugly fit around your chest and note the measurement where the tape meets the initial reference point. Use this measurement to select the appropriate size of compression shorts. Check the size chart on the product packaging or online product details to ensure a proper fit.

Cut the two legs of the shorts. Leave about 15 to 20 cm of the legs on both sides, then use sharp scissors to cut across. At this point, the compression shorts will resemble a pair of briefs.

Cut a hole at the bottom of the shorts for your head. Start by identifying the bottom of the compression shorts. Then, flatten them so they lie neatly on a flat surface. Use scissors to cut a hole at the bottom, just large enough for your head to fit through.
- If the hole isn't big enough, use the scissors to widen it further.

Pull the compression shorts over your head like a small shirt. Slide your head through the hole at the bottom, and insert your arms into the previously cut "leg" sections. Pull the back of the shorts down to chest level to secure them.
- This method works best when worn over a sports bra.
Using Other Materials to Create a Chest Binder

Wearing multiple layers of sports bras without padding can also help achieve a relatively flat chest. Opt for sports bras without padding, as they are effective for flattening the chest. If your chest is relatively large, you can layer another sports bra for added support. Choose a slightly smaller sports bra, but avoid one that's too tight, as it may restrict your breathing.
- Additionally, some companies produce shaping vests that help straighten your back while compressing your chest.

Back braces or lumbar supports are an easy method to conceal the chest. These products often come with very secure Velcro straps. Position the Velcro strap under your arms to minimize visibility, then tighten the brace to flatten the chest.

Compression shirts are another straightforward solution for chest concealment. Similar to compression shorts or tights, these shirts fit snugly against the body. The fabric tends to flatten the chest, allowing you to wear any type of shirt over it. Compression shirts are available at sportswear stores.
Safe chest binding

Remove your chest binder when sleeping. Wearing a binder 24/7 can lead to skin issues and other medical symptoms. It's important to let your body relax for at least a few hours each day.

Avoid wearing a chest binder during exercise if possible. While sports bras are suitable for workouts, other products like back braces or even compression shorts can be quite uncomfortable. They can restrict your movement and make normal breathing difficult.

Dust baby powder inside your chest binder to prevent friction-related injuries. If the binder causes redness or irritation by rubbing against your skin, a light layer of baby powder can help. Apply a thin coat to the binder or your body before putting it on.

Avoid using medical elastic bandages or adhesive tape for chest binding. These products lack proper stretch and can lead to severe issues. Adhesive tape may stick unevenly and harm the skin, while medical bandages tighten excessively during movement, making breathing difficult.
Advice
- Pay attention to your body. If you feel pain or have trouble breathing while binding, stop immediately and try other methods.
- Whenever possible, opt for a professionally designed chest binder instead of DIY solutions. These products are tailored for chest concealment and are much safer.
Warning
- Improper chest binding can result in permanent injuries, including the inability to undergo breast surgery if your body sustains severe damage. If you feel uneasy, it's best to minimize such practices to safeguard your long-term health.
