The Challenge

The success of Wacoal, the leading North American intimate apparel brand, is deep rooted in customer service and helping women find bras that complement their size and shape. With the shift to online shopping, Wacoal knew they had to do more to help customers find their best fit online. Bra shopping is a daunting task for many women, between figuring out their size to knowing what style to buy. Wacoal know from 35+ years in the business that when you truly help a customer figure out her size and shape, she will be a loyal customer for life. They searched to find the right partner who could develop a digital sizing tool to help them broaden their reach and empower women to have control over their bra shopping experience.

The Solution

Wacoal wanted to be the first intimate apparel brand to evolve bra size calculation by incorporating more points of measure than a consumer would usually be able to take accurately on her own. By partnering with Sizer, Wacoal was able to remove human error and develop a proprietary size algorithm that increases accuracy by 300%.

Bra measurements are very specific and a 5mm difference can cause a size recommendation error. After scouring the digital measurement space and running accuracy trials with several companies, Wacoal selected Sizer as its digital partner to develop the mybraFit™ app, due to its highest level of accuracy and simple, easy to use consumer interface.

“Following an intense market study, we chose to collaborate with Sizer as our digital measuring partner, due to their unmatched body measurement accuracy and convenient and user-friendly solution”
