Good compromise between a regular and a vertical wire because it’s comes up higher at the bridge but still flares out (and is shorter) at the arm to prevent digging. Use the same size you would in our regular underwires. These wires are your standard regular length bra underwire for use in most classic bra patterns. 5mm shorter than our R2 wires. If you’re not quite an omega style breast needing a true vertical wire you might find these to be just the right fit. Compared to our R series wires these are higher in the front and lower at the underarm so they really cover a common fit issue.
This wire is the same basic shape as our R1 and R2 wires. It is the same length as the R1 wires but they are 10mm shorter at the front and 10mm higher at the arm. These are good for a slightly lower cut bra but are not as short as a demi or plunge wire which are 20mm+ shorter than a regular wire.
A vertical size underwire that is more U shaped than a regular underwire and the front arm swings up at the center front in a vertical fashion. Perfect if you have omega shaped breasts common with large cup sizes on smaller frames. You might need to go a size or two up from your regular underwire size since this wire is narrower than a R1/R2 of the same size.
These are demi cup or balconette style underwires perfect for creating a bra with a lower neckline that your standard day bra. This is the style of wire you need to create those sexy Victoria Secret style bras. See also our plunge / pushup bra wires for an even lower 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 20-30mm shorter than our regular day wear wires.
These are similar in shape to our demi underwires but they are more flared at both ends and are 15mm shorter at the underarm. Victoria Secret uses this style of underwire a lot in their wired bralettes and some of their halter neck style. A good wire choice for certain swimsuit styles.
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. 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.
This is the wire you need if you are looking to make a strapless bra that fits. In a strapless bra underwire the front and arm of the wire are exactly the same length to ensure you get the support and coverage that you need. You simply can’t make a strapless bra without one. This style comes in two lengths the S1 (this listing) or the S2 which is 10mm shorter but the same shape. Lengthwise the S1 is the same length as a R1 of the same size but is higher in the front and lower at the arm compared to a regular day bra wire (R1/R2)
These monowires are low in the front and high at the arm for the perfect pushup effect. Similar in sizing to our R1 wires.
