+Proprietary "Half sizes" provide a near custom fit!
It turns out that 50% of women sizes A-D fall in between standard cup sizes, so we invented half cup sizing. Ever had a hunch you were an in-betweener? Now you’ll never have to settle for a bra that only half fits.
We developed our Breast Shape Dictionary (available on our website) because we think perfect fit is more than a numbered size. With your shape in mind, you’re better equipped to pick styles that fit your body like a glove.
+Made with real women’s measurements.
Instead of using standard industry measurements and grading them up and down to create each bra size, we fit all of our sizes on real women. These fittings let us design each bra size to be a more precise fit (like shorter strap lengths for better lift on larger sizes, or a wider width between cups on smaller sizes). Sure, it’s more work. But we’re up to the task.
+Curious about our sizing technology? What about security?
All you’ll need is a spare five minutes, a supportive bra, a tank top and a wall-mounted mirror. Photos aren't stored in "the cloud", never uploaded anywhere, and in fact aren't even stored on your photo reel. They are used for a split second during processing, which happens natively, and then they are gone.

Great, App! Great, Bras!
ThirdLove is my new favorite bra brand. The app successfully helped me get into the right size as I had been wearing the wrong size for years! App is easy to use and I love the live chat feature to be able to chat with a fit stylist!
Super buggy- refuses to accept address
I LOVE the idea of this app since I've had bra fit issues nearly my entire life. Unfortunately due to the buggy nature of this app I've been unable to complete my purchase because it refuses to accept my address (I've tried 3 different ones!). Also I had a lot of trouble getting/taking the photos. Please fix the app, I really would love for this to be my new go-to!
Love this company
Measures you just with your phone. So easy and accurate! Can place orders through the app as well well! And their bras are adorable and the most comfortable I've ever owned.
