Choosing the right bra size is a task that brings many women upside down. It depends on the contour, the shape, the back... Many times, the wrong sizes are used simply because it is unknown how to get the right one, in fact, El País published that 70% of women do not know how to buy bras of their correct size .

But maybe this question can be solved quickly. It has been thanks to TikTok, where a method that is revolutionizing the users of the social network has gone viral.

This Spanish startup, trusted by 400 brands from around the world, wants to end size differences in online stores and has grown 140% in the midst of a pandemic

It's called: A Bra That Fits, a kind of calculator that helps you choose your correct bra size, and although it already existed since 2010, it has become fashionable again.

The cause of this reappearance is the lingerie model Madison Alexandra, who uploaded a video talking about this application a few weeks ago.

In a lighthearted and humorous tone, she used a sock full of rice as a breast, and gave an example from her own experience. "How is it possible for a bra to be big and small at the same time?" It is the question that Madison asks herself before presenting A Bra That Fits.

The model stresses that each breast is different so, although at first glance it seems that two people should wear the same size, their backs, contours, and the projection of the breasts in different positions make each one need a different bra, according to your needs.

For this reason, in the application, they will ask you to measure your contour face down, lying down or standing. In addition, the creators of the original calculator also have a space on Reddit, with a thread where they show a basic guide to better understand everything that includes calculating your bra size and answering many why.
