Deep Plunge U-Shape Longline Bra – Bonded Mesh, Push-Up Bustier

A deep plunge U-shape longline bra engineered to disappear under the most revealing necklines — the dramatic center cut and wide longline band sit cleanly under a deep V dress, a low-cut bodysuit, or a backless evening gown. The bonded microfiber lower band has heat-sealed seamless edges that won't show through thin or silky fabrics, and the fine-mesh cup overlays add a subtle ribbed texture without bulk.

The U-shaped underwire frame at the center front is the structural key — it keeps the deep plunge from collapsing while supporting the cups, and the padded molded cups add a push-up lift for a defined cleavage line. Thin adjustable straps with dark gunmetal sliders sit cleanly on the shoulders, and the longline band extends below the bust to smooth the upper waist and provide a tucked-in look without a separate shapewear piece.
