How Do Bra Extenders Work?

Often used as a quick fix, bra extenders are small pieces of fabric with hook and eye closures that attach to your current bra to extend the length of the band. This bra hack can come in handy when in a pinch, but oftentimes, the best bras don’t need one to begin with. For those curious about bra extenders, here are a few pros and cons for using this bra accessory.

Pros and Cons

Pros: Bra extenders can elongate the band if the band feels tight or provide more hook options if you find yourself between band sizes (For example, a 32 band is too small and a 34 band is too big). This can be an easy temporary fix if you’re experiencing any weight fluctuations and changes in band size.

Cons: Using a bra extender can distort the bra, affecting the fit and longevity. This is similar to using a racerback bra clip on a non-racerback bra style, which can pull on the band and straps. The small rectangular fabric may not stay securely attached to your bra as well.

How Long Can You Use Bra Extenders For?

While bra extenders are great for a quick fix, they are only temporary solutions. Although they can solve band size problems, they often create new ones. Bra extenders affect the design of the bra, moving the bra straps closer to your shoulders and changing the tension of the bra. This can cause your shoulder straps to slip and distort the fit of the bra.

How Many Inches Do Bra Extenders Add?

In general, a bra strap extender can add up to about 3 inches onto your bra’s band length. Just as all bras are created differently, all bra extenders are created differently as well and some may add more or less length depending on the design.

Our Advice

Focus on finding the right bra size in the original bra. Our designers can attest to the thought that goes into designing a bra with all the right contributing features to ensure a supportive and flattering fit. The ideal fit and support should come from the bra alone.

If you find that you’re in between band sizes, we recommend wearing the smaller band as it’ll stretch out with regular wear. The band shouldn’t feel too tight to the point of discomfort, but might temporarily feel snug to start.

If you’re in need of a quick fix, bra extenders can be an easy, short-term solution (emphasis on “short-term”). But bra hacks like this aren’t necessary when you already have a great-fitting bra.
