Turn heads with the Ultra Boost Plungy Bra, the push-up bra engineered for maximum lift and a boldly defined, deep plunge silhouette. A single underwire delivers focused support and enhanced shaping, bringing the bust together for a naturally fuller, boosted look — while smooth, sculpting cups frame a flattering neckline that feels as good as it looks. Confident, sensual, and perfectly engineered, this is your go-to bra for low-cut outfits and statement looks that demand impact.
Single underwire for focused lift and shaping: The precisely positioned underwire targets support exactly where it’s needed, bringing the bust together for a beautifully boosted, fuller appearance that enhances your natural shape.
Deep plunge cut for daring necklines: Specially designed to complement the lowest of necklines, the bold plunge silhouette makes the Ultra Boost Plungy Bra the ultimate companion for low-cut dresses, tops, and any look that calls for a little extra drama.
Smooth sculpting cups for a flattering finish: The sleek, form-fitting cups contour gently to the bust, creating a polished, seamless neckline while remaining lightweight and comfortable against the skin throughout the day.
Push-up style for a naturally fuller look: The push-up design lifts and enhances the bust from every angle, delivering a confident, sensual silhouette that makes every outfit feel like a statement.
Fabric: 88% polyamide, 12% elastane for stretch and support
Adhesive: 100% medical polyolefin glue
