Triangle Swimsuit and Bra Inserts, 1-Piece

Need a simple way to add coverage inside compatible swimwear or lingerie?

Swimsuit and bra fabrics do not always provide the level of coverage or shape you prefer, especially when you are packing for a holiday, replacing a missing pad, or styling a different neckline. This removable triangle insert gives you a lightweight accessory to place inside compatible swimwear, bras, or similar garments. It is an easy option to keep in a lingerie drawer or travel pouch when you want a little more flexibility from the pieces you already own.

The insert is listed in a range of solid colours including green, grey, black, nude, and pink. Its triangle shape is designed to sit inside a compatible cup or sewn-in pocket, but the final fit will depend on the garment’s opening, pocket size, fabric, and the way you position the insert. Check the product images and your garment before ordering, and test the insert while moving normally to make sure it stays comfortable and secure.

A removable accessory for swimwear and lingerie

The product information lists a wire-free support type, full-cup shape, solid pattern, and push-up bra style. Those are design descriptors, not a promise of a particular lift, cup conversion, body change, or fit across every garment. The product detail lists sponge as the material, while the specification section identifies cotton, so both material descriptions are preserved here. Use it only as an insert in a compatible garment, not as a standalone item or medical support.

Compare the guide with your garment

The supplied guide lists M for a stated weight range of 45–52.5 kg, L for 50–60 kg, XL for 65–72.5 kg, and 2XL for 70–90 kg. Shopify’s available option is labelled 1XL, while the source guide uses XL, so compare the option labels and product images carefully. Weight-based guidance is only a rough reference and cannot replace checking the insert against the cup pocket or garment opening.

Before wearing, place the insert inside the garment and check that it lies flat without folding, pinching, or shifting. Do not force it into a pocket that is too small, and do not use it if the material is damaged or if it causes discomfort. For care, follow the supplied instructions, wash gently when appropriate, let the insert dry fully, and store it flat so the shape is not permanently creased. Keep colours separate during the first wash if recommended by the care guidance.

This small accessory is useful when you want to refresh compatible swimwear or lingerie without replacing the whole garment. It offers a removable way to experiment with coverage and fit, while leaving the final result to the garment, the insert position, and your own comfort.
