The Engineering Behind the Perfect Bra Fit

The Perfect Base Layer

Ever wonder why bra comfort is so hard to find? Good bra design doesn't come easily, and most companies fall short during their design and testing phases. To craft a bra that women actually want to wear, the team here at Evelyn & Bobbie uses intricate engineering principles to create our products. We're committed to ensuring our bras offer unparalleled comfort through the perfect bra fit.

Ancient History: Traditional Underwire Bras

The first U.S. patent for an underwire bra was issued in 1893 to Marie Tucek. The patent included separate pockets for each breast. A metal plate was involved in the design, and shoulder straps were included to provide support. 

Sound comfortable? It probably wasn't.

Bras haven’t come that far since those early models, and for many bra companies, innovation has stalled. Evelyn & Bobbie is here to change that.

Introduction to EB's Unique Design Philosophy

Why is it so hard to find the perfect bra? Bras must fit against the body comfortably and support the breasts without digging into your delicate trapezius muscles or uncomfortable wires digging into your ribcage. Every body is unique, so comfort comes from bras that can conform to your beautiful, unique shape, hugging and supporting at the same time. To ensure a perfect bra fit in just 7 easy sizes, our team of designers uses creativity, innovation, and a ton of customer research.

The Evelyn & Bobbie Approach

Comfort & Support

What makes a bra supportive? Ultimately, it comes down to the internal structure, strength, and location of the cups. Our patented EB Core® technology doesn’t just remove the underwire, it replaces it with a magically supportive and comfortable 3D sling. Years of research & engineering went into our patented design to find the perfect blend of comfort and support while appearing seamless and invisible under clothing.

Shape & Adjustability 

Our research and design team here at Evelyn & Bobbie always performs multiple wear tests with a wide variety of models representing each size. In fact, at least 28 individuals are involved in testing, from XS to 3XL. Wear-testers try the bra and provide us with valuable and detailed feedback that our team reviews meticulously. At least 13 measurements are taken on each wear-tester, resulting in over 364 data points to guide our team while making adjustments.

Adjustments may be as minor as 1/18th of an inch based on feedback from customers just like you. This is a meticulous process that relies heavily on both qualitative and quantitative research. Each design goes through eight iterations before it's considered for the final product, including three to four prototypes, a fit test, a second fit test, a wear test, and then a second wear test before entering pre-production.

If the pre-production data is positive, then the bra goes to production.Feedback must be overwhelmingly positive before a product is made. So, if feedback from wear testers is not positive, the product doesn't get made. Once a bra is on the market, our team monitors reviews, returns data, and talks to customers, all to be sure that our products offer a perfect bra fit.

Engineering Principles in Action

Plunge & Push-Up

We've designed our products to custom mold to your unique shape after the first three wears. And because of our four-way stretch technology, one size can fit a range of bodies. Even if you gain or lose 10 pounds (we’ve all been there!), you’ll likely still wear the same Evelyn & Bobbie size.
