Why Does My Bra Gap in the Front?

Bra fit issues are a universal blight among bra-wearers. In fact, a 2008 study has shown that roughly 80% of women are wearing the wrong bra size. Perhaps no bra fit issue is as prominent, however, as bra cup gaps.

Cup gaping refers to any space left at the top of the cup after the bra has been put on. It usually signifies that the bra is the wrong size or style, though it could also be an issue with the straps.

Keep reading to learn what causes bra gaping, how to avoid it, and what steps to take if you’re already experiencing this common issue. Your best bra fit is out there waiting for you!


Why is My Bra Gaping at the Top?

There are a few potential causes of bra cup gaps:

  • The cup size is too large for you
  • The bra style is not a good match for your breast shape
  • The straps are too stretched out

Discovering the root cause of your bra gap is critical in finding a solution. After all, there’s no need to throw out all your old bras if the issue is just loose straps. Likewise, if adjusting the straps doesn’t work, you might need to replace your current bras with ones that fit better.

How to Avoid Bra Cup Gap

No one wants to walk around with a bra cup gap. Luckily, there are ways to avoid this predicament.


Determine Your Cup and Band Size

Wearing the wrong bra size is the most common reason for gaping at the top of the cup. We recommend getting your bra size professionally measured at one of our stores or taking our Fitting Room Quiz online to find your perfect size before making a purchase. This will ensure you get the best-fitting bra every time.


Choose Your Ideal Bra Style

Not all breasts are created equal (though they are all equally beautiful) and depending on your breast shape, some styles will fit and flatter you better than others. There are several bra styles to choose from, so we recommend trying on a few different silhouettes to find the perfect bra that makes you look and feel great.

If you’re struggling with bra cup gaps, you may need to consider opting for a balconette, demi, or push-up bra. Balconette and demi bras tend to have less cup to fill, making them better for slender breast shapes. Push-up bras use extra padding to help even smaller breasts fill in the entire bra cup.


Replace Worn Bras with New Ones

The more you wear a bra, the more it loses its elasticity and integrity. This can result in cup gaps over time as the bra becomes less able to support your breasts. We recommend replacing your bra every 6 months to a year, depending on how often you wear them. Avoid bra cup gaps by replacing your worn out bras with new ones on a regular basis.

How to Fix Bra Cup Gap

If you’re already experiencing bra cup gaps, there are steps you can take to fix the problem.


Adjust Your Straps

Sometimes, cup gaping is the result of the bra straps loosening or losing their elasticity. Try to tighten the straps and see whether this remedies the cup gap.


Go Down a Cup Size

If you notice that your breast rests at the bottom of the cup, it’s possible that your bra is simply too big for you. Go down a cup size and determine whether the fit is any better. ThirdLove offers half cup sizes, as well, so you’re more likely to find your optimal fit.


Try Other Bra Styles

The style of bra has a major impact on how the bra fits, and different styles tend to work better for different breast shapes. If you’re experiencing bra cup gaps, you’ll likely benefit from trying bra styles better suited for slender breasts:

  • Balconette
  • Demi
  • Push-up


Change How You Wear Your Bra

The way you put your bra on influences the way it fits you. For the perfect fit, ensure your breasts fill their respective cups entirely and align your nipples with the center of the cups. This is the proper way to wear a bra, so if cup gaps remain, it means the bra is too big or the straps are too loose.
