The Science: Behind Our BreastBeautiful™ Promise

The Science: Behind Our BreastBeautiful™ Promise

At Up All Nightie, we believe every woman deserves to feel beautifully lifted and supported—even at night. But for women with larger, heavier breasts, reliable and comfortable nighttime support has long been hard to find. That’s why we created something revolutionary: the BreastBeautiful™ Promise, backed by our patented Bodice Support System.

What Makes It Different?

Supporting D+ cup sizes is challenging and requires more than just good intentions. It demands smart engineering, strategic design, and a deep understanding of how to support larger breasts, especially during sleep. That’s why our patented bodice system delivers multi-directional lift—horizontal, diagonal and vertical—and 360° support across the entire garment—front, back, and sides—for a naturally round, beautifully lifted shape that lasts all night.

Our Secret? Smart Fabric Engineering.

Our bodice combines high-performance stretch and non-stretch fabrics, precisely layered, contoured and connected to move with your body while providing targeted structure—without the discomfort of wires or hardware. The result is a 360° support system that lifts, shapes, and stabilizes comfortably and confidently, no matter your cup size.

Inside the Technology: A Closer Look

  • Stabilizing Under-Bust Foundation

A structured, wire-free framework anchors each breast from below along the cup and breast root, providing a stable base that resists sagging and prevents breasts from falling below.

  • Plush-Back 360° Elastic Support Band

This soft full-circumference band secures all support elements in place—gently anchoring without digging or shifting.

  • Curved Support Slings + Contoured 3-Piece Cups

Internal slings cradle your breasts following your natural curves to enhance projection and volume without a stiff, artificial "push-up" look. The 3-piece cups contour precisely for a beautiful, round shape.

  • Supportive Power Stretch Back + Wider Non-Adjustable Straps

Acting as a unified lifting system, these elements work together to distribute breast weight evenly from the cups, over the shoulders and across the back, enhancing lift and preventing ride-up without the discomfort of adjustable hardware. 

The Result? A Nightie That Delivers WOW Lift—But Feels Like a Dream
