Plastic-boned corselettes are popular in modern fashion corsets and costumes, where flexibility and ease of wear are essential. However, plastic boning may not provide as much support as steel boning in tightly laced or heavily structured corsets. Plastic boning weakens when bent and eventually snaps after extended wear, which can be dangerous. It is also inadequate at providing support and develops weak points when you bend and sit. For waist training, steel boned corsets are recommended.
| Characteristics | Values |
|---|---|
| Comfort | Plastic boning is softer and more pliable than steel boning, and is therefore initially more comfortable. However, plastic bones can develop weak points when bent, which can be uncomfortable. |
| Support | Plastic boning does not provide the same level of support as steel boning, which supports the body in a way that plastic cannot. |
| Durability | Plastic boning weakens when bent and can eventually snap after extended wear. |
| Safety | Plastic boning is less safe than steel boning because it can pierce the skin if it breaks. |
| Use case | Plastic boning is suitable for lingerie and stage or party costumes, but not for corset training. |

What You'll Learn

Plastic boning weakens with bending, eventually snapping
Plastic boning weakens with bending and can eventually snap, so it is not recommended for corset training. When sitting in a plastic-boned corset, the plastic bones will develop weak points and sharp bends or kinks. These weak points will cause the corset to lose its shape and the weak points will continue to kink each time the corset is worn, causing discomfort. Eventually, the bone will break, which can be dangerous as it may pierce the skin through the lining of the corset.
For this reason, steel boning is often preferred over plastic boning. Steel boning does not develop weak points and will spring back to its original shape when bent. It provides more support than plastic boning and is more comfortable for the wearer.
However, there are different types of steel boning to consider. Sprung steel boning is a flat strip of solid steel, rounded at the ends and usually coated in plastic to prevent rust. It provides a smoother silhouette and more support than spiral steel boning. Spiral steel boning, on the other hand, is made of two steel wires spiralled together, providing more flexibility and freedom of movement. It is often used at the sides of corsets to allow for ease of movement, while sprung steel is used in the front to flatten the tummy.
In conclusion, while plastic boning may be more affordable and accessible than steel boning, it is not suitable for corset training due to its tendency to weaken and snap with repeated bending. Steel boning, particularly sprung steel, is a more durable and comfortable option for those seeking support and smooth silhouette. For added flexibility, spiral steel boning can be incorporated into the design as well.

Plastic boning is unsuitable for corset training
Corset training requires a boning material that is durable and can provide adequate support to the body. Plastic boning is unsuitable for corset training because it weakens when bent and develops weak points. Plastic boned corsets are therefore likely to break after extended wear, which can be dangerous as the broken bone can pierce the skin. Plastic boning is also unable to provide the same level of support as steel boning in tightly laced or heavily structured corsets.
Plastic boning is made from materials like polyester or nylon, making it a more lightweight option compared to steel boning. It is favoured in modern fashion corsets and costumes where flexibility and ease of wear are important. However, for waist training, steel boned corsets are necessary as they provide the required level of support and durability.
When it comes to the type of steel boning, there are two main options: sprung steel and spiral steel. Sprung steel comes as a flat strip of solid steel, rounded at the ends and usually coated in plastic to prevent rust. It provides a smoother silhouette and slightly more support than spiral steel. Spiral steel, on the other hand, is made of two steel wires spiralled together, allowing for a greater range of motion. It is often used at the sides of corsets to allow for ease of movement, while sprung steel is used at the front to flatten the tummy.
While plastic boning may be suitable for lingerie, costumes, or mock-up corsets, it is not recommended for corset training due to its lack of durability and inadequate support. Steel boning is the preferred choice for corset training as it provides the necessary structure, durability, and support to effectively shape and train the body.
In summary, plastic boning is unsuitable for corset training due to its weakness in providing support, durability issues, and potential safety hazards. Steel boning, particularly sprung and spiral steel, is the preferred choice for corset training as it offers superior support, flexibility, and durability, ensuring a comfortable and effective training experience.

Steel boning offers more support
The type of boning used in a corset is crucial to its function and appearance. Boning gives corsets their shape, strength, and distinctive hourglass silhouette. While plastic boning may be more comfortable due to its softness and pliability, it is not suitable for corset training as it weakens over time and can lead to an unsightly appearance and discomfort. Steel boning, despite its reputation for being harsh and unyielding, provides superior support and maintains its shape, resulting in a more elegant and seamless look.
When deciding between steel and plastic boning, it is essential to consider the purpose of the corset. If the corset is for waist training or body shaping, steel boning is the best option as it provides the necessary rigidity and support. Plastic boning may be suitable for lingerie or costumes where flexibility and comfort are prioritised over support. However, even in these cases, the durability of plastic boning is questionable, as it tends to develop weak points and break with extended wear.
Ultimately, steel boning offers more support and durability than plastic boning, making it the preferred choice for corset training and body shaping. While plastic boning may provide some flexibility and comfort, it falls short in terms of long-term support and maintaining the structure of the corset. For those seeking the benefits of both worlds, a combination of spiral and spring steel boning can provide a balance of support, rigidity, and flexibility, depending on the placement and thickness of the boning.

Rigilene boning is a strong, long-lasting plastic alternative
Plastic boning is often used in corsets because it is softer and more pliable than steel boning, which makes it more comfortable. However, plastic boning is largely inadequate at providing support. Plastic bones develop weak points when bent, and will eventually snap after extended wear. This can be dangerous, as a broken plastic bone can pierce the skin through the lining of a corset. Plastic boning is therefore considered unsuitable for corset training.
Rigilene boning is a strong plastic alternative that is known for being supportive and long-lasting. It has a ribbed design, which makes it stiff and hard to bend. Rigilene boning is often used in corsets that require a higher level of support, particularly at the seams and edges. The rigidity of Rigilene boning means that the corset keeps its shape even when the wearer is engaging in tough activities. However, the stiffness of Rigilene boning may limit certain movements compared to more flexible options.
Rigilene boning is made from materials like polyester or nylon. It is lightweight, highly flexible, and extremely durable. Rigilene boning can be sewn through, and has soft edges that make it easy to sew by hand or machine. The length of Rigilene boning can be adjusted by filing the edges down for a soft finish. However, Rigilene boning cannot be sewn in curved channels, only straight seams.
Overall, Rigilene boning is a strong, long-lasting plastic alternative to other types of boning. It is ideal for corsets that require a high level of support, but the rigidity of the boning may restrict certain movements.

Plastic boning is popular in modern fashion corsets
Plastic boning is a popular choice for modern fashion corsets. It is made from materials like polyester or nylon, offering a lightweight alternative to steel boning. Plastic boning is flexible, comfortable, and still allows a corset to maintain its shape. This makes it ideal for costumes and fashion corsets, where flexibility and ease of wear are important.
However, plastic boning is inadequate for providing support in tightly laced or heavily structured corsets. Plastic weakens when bent and can develop weak points, eventually snapping after extended wear. This can cause the corset to lose its shape and may even be dangerous, as a broken bone can pierce the lining of the corset and the wearer's skin.
For waist training or heavily structured corsets, steel boning is necessary to provide adequate support. Steel boning comes in two varieties: flat spring steel and spiral steel. Spiral steel is more flexible than flat spring steel, as it can bend in two directions, but both varieties are rigid lengthwise.
While plastic boning may not be suitable for all types of corsets, it remains a popular choice for modern fashion corsets due to its flexibility, comfort, and ability to maintain the shape of the garment.
