These are plunge / push up style underwires for creating very low cut or push up style bras. This is the style of wire you need to create those low cut WONDER BRA style bras. See also our demi cup / balconette bra wires for an slightly higher neckline. Compared to a regular day wear wire these are lower in the front and slightly lower at the arm but the angle from the balance point of the wire to the arm is a steeper angle than a regular round wire. They are 40-50mm shorter than our regular day wear wires and about 18-20mm shorter than our demi cup underwires

Check out our regular wires, vertical, demi, strapless and our RHF1 High Front wires also. We are expanding our line of underwires to help you meet all your fitting needs since no two pair of breasts are exactly right and we understand WHY you make bras.

Due to COVID-19 and hygiene reasons underwires are not returnable. Please refer to underwire sizing charts.
