Our team of Fit Specialists is here to help you find bras that feel like they were made for you. We’ve worked with thousands of women find their perfect fit, so we’re sharing some of our best advice here.


First of all, you’re in good company. Although 40% of women who take our Fit Finder® Quiz classify themselves as having asymmetric breasts, the numbers are actually much higher. Since no one is perfectly symmetrical, essentially 100% of women have asymmetry to some degree. Love your asymmetry? So do we! Want a more even silhouette? We can help with that, too.

How to fix one breast that’s bigger than the other.

We get this question from customers and a great way to get a balanced look is to add a little lift to the smaller breast. The 24/7™ Classic Uplift Plunge Bra is a stellar option for breasts of all shapes and sizes for a few reasons.

The Classic Uplift Plunge’s secret to working with asymmetry is removable inserts. Wearing both inserts gives you lift when you want it, like an on-demand push-up bra. However, you can also wear the insert on just one side, giving your smaller breast a boost. The bra’s soft and beautiful mesh overlay provides sheer coverage and support while the deep neckline looks great on everyone.

How to measure for your bra size with asymmetrical breasts.

Getting measured for a bra when you have asymmetrical breasts doesn’t have to be tricky. When taking the Fit Finder Quiz, we recommend answering the fit questions based on your larger breast. In general, it’s easier to size a bra to the larger breast since it’ll wear more comfortably while still having room to adjust to the smaller breast. Image the opposite scenario where you’re trying to fit the larger breast into a smaller cup! You’ll most likely experience overflow.

In your new size, the larger breast should fit comfortably in the cup without gaping or overflow. For the smaller breast, small inserts, such as the ones in the Classic Uplift Plunge, can be used to add volume so it’s fully supported and fills the cup for an even look.

Asymmetry or not, give the 24/7 Classic Uplift Plunge a try. It’s a superstar bra with versatility and comfort that will quickly make its way into your daily rotation. Also, see our sister styles including 24/7 Lace Contour Plunge and the Everyday Lace Uplift Plunge Bra for more options – both of which also have removable inserts!
