Bra Separator Wire – V-Wire, U-Wire & Custom Metal Shapes

HS ALF manufactures custom-shaped metal bra separator wires for lingerie, bras, swimwear, corsetry, bridalwear, eveningwear, dancewear, costumes and other structured garments. The product is commonly searched as a V-wire bra separator, bra separator wire, metal bra separator or plunge support wire. Unlike a conventional cup underwire, this component is positioned at the center front, neckline, cut-out or another engineered opening to help the fabric retain the intended design line. The wire acts as an internal shaping element. When the garment requires a deep V, narrow V, rounded U, square U, curved V, M, S or another controlled geometry, the separator is enclosed in a channel, casing or reinforced fabric area so the opening follows the shape engineered into the metal. The same principle can be applied to selected back openings and decorative cut-outs in dresses or occasionwear where the garment must remain in a defined form instead of collapsing or spreading. For plunge bras and lingerie, the separator can work together with conventional bra underwires, side boning or other structural components. Its purpose is not simply breast support; it is geometric control of the center-front or cut-out area. Correct selection therefore depends on the required height, top width, depth, radius, three-dimensional curvature, wire section, end treatment and the way the component will be enclosed in the garment. HS ALF can develop multiple standard and project-specific shapes including V, U, narrow V, wide V, rounded V, square U, deep U, curved U, M, S, straight and asymmetric forms. Buyers can provide a technical drawing, reference sample, garment pattern or target dimensions. The requested geometry can then be evaluated for sampling and repeat production. For industrial sourcing, consistent geometry is critical. HS ALF focuses on repeatability between samples and bulk production, smooth finished ends, stable forming, dimensional control and compatibility with industrial sewing construction. Projects can be supplied for OEM, ODM, private-label and bulk B2B programs for lingerie brands, bra factories, swimwear manufacturers, bridalwear producers, costume workshops and apparel sourcing teams. To request a technical quotation, specify the intended garment, required shape, overall height, top width, opening depth, wire diameter or section where known, flat or 3D curvature, end-tip requirement, target finish, reference drawing/sample and estimated order quantity. This allows the separator wire to be matched to the actual design rather than selected only by a generic V-wire size.
