The technology we use, takes two-dimensional images, like a photo. And turns it into three-dimensional data. Reporter: Here's how it works. You take front and side pictures, wearing a tank top. The app even tells you when you have the right angle. The company says it only takes seconds for the app to size you. The only catch -- it doesn't tell you your exact size. Reporter: Instead, it routes you to an online store, where all of the bras are your perfect fit. Danny tested thirdlove. It came in the mail. And it fit perfectly. Reporter: Other women we met are still a bit weary. You have to take photographs of yourself and send it to someone you don't know. Reporter: The makers of the app insist their site is secure.

Old-school in this case is the best way. Absolutely. Reporter: What measures up best? Old-school awkwardness? Or touchless technology? The women we met say the right fit is what makes you feel most comfortable. For "good morning america," aditi roy, abc news, new york.
