When it comes to bras, one size certainly does not fit all. Yet, most ready-to-wear bras rely on a standardized sizing system that, quite frankly, is deeply flawed. The traditional method uses two dependent measurements—band size and cup size—that only account for the horizontal circumference of your body. But here’s the catch: breasts aren’t just horizontal shapes. They have depth, volume, and unique contours that standard sizes simply don't accommodate.

The Limits of Horizontal Measurements
Traditional bra sizing starts with measuring your band size, the number that represents the circumference of your ribcage just under your bust. Next comes the cup size, which is determined by the difference between the circumference of your bust and your band. These measurements are then used to assign a size like 34B, 36C, and so on.

But here's the problem: these numbers assume a standardized shape that doesn’t exist for most women. For example, two women might both measure a 34-inch band and a 37-inch bust, leading them both to a 34C size. However, one woman might have a fuller, rounder shape, while the other has a shallower, wider bust. They’ll end up with the same size bra, but it won’t fit them both well. The bra might gap on one and cause spillage on the other because the measurements don’t account for the unique shape and volume of each woman's breasts.

The Impact of Poor Fit
When your bra doesn’t fit properly, it’s not just uncomfortable—it can lead to a host of other issues. Here’s what happens when the standard sizing fails:

Riding Back Band:

The band is supposed to provide most of the support, but when it doesn't fit correctly, you might find yourself tightening your straps all the way to compensate. This can cause the back band to ride up, leading to discomfort and a lack of proper support. The band should stay firmly in place, no more than 2 cm off your body, to ensure the bra is providing the support you need.

Gaping or Spilling:

If your bra doesn’t match your breast shape, you might experience gaping at the top of the cups or spillage over the sides. This not only affects how your clothes look but also how comfortable you feel throughout the day.

Falling Straps:

Falling straps are a common issue when a bra isn’t fitted to your shoulders correctly. Even if the straps are tightened all the way, if the bra isn't the right fit for your body, the straps can still slip off your shoulders. This constant adjustment isn’t just annoying; it’s a clear sign that your bra isn’t properly supporting you.

The Solution: Custom Fit

The solution to these common issues isn’t trying on endless sizes and hoping for the best—it’s going custom. At DOUBL, we believe that your bra should fit you like a second skin, accommodating not just the horizontal measurements but the unique shape and volume of your breasts. Our custom-fit bras are designed to stay no more than 2 cm off your body, ensure no gaping or spilling, and keep your straps securely in place. Plus, they’re fitted specifically to your back, shoulders, and bust, ensuring complete comfort and support where you need it most. Because when your bra fits perfectly, you can focus on what really matters—feeling confident, comfortable, and supported every day.

Ready-to-wear sizing may be the norm, but it’s not the best solution. Your body deserves more than a one-size-fits-all approach. Invest in a custom fit that’s made just for you, and experience the difference for yourself.
