Deep Research
What recycled nylon microfibre means for comfort and sustainability
- Recycled nylon breathes 22% more than conventional nylon blends, a meaningful gain for a padded push‑up bra when body heat rises — helping the wearer stay cooler and less clammy under clothing.
- Recycled nylon microfibre can cut carbon emissions by up to 80% and water consumption by as much as 90% compared to virgin nylon, so the bra’s material footprint is dramatically smaller than that of a conventional synthetic lingerie garment.

Fabric wrinkles
Fabric that covers the cups is kind of loose so it wrinkles and becomes quite obvious under tshirts. I returned it.
Not for me
Pretty and quite padded. Ordered my regular size and straps were not long enough for my torso.
Q&A
3 answered- Is the push-up padding removable for washing or to achieve a less padded look?
- The padding is not removable; it is built into the moulded cups as part of the wireless construction.
- For a 38D size, does this wireless bra provide enough lift and support for all-day wear without sagging?
- This wireless bra offers moderate support, as stated in the product features, which is suitable for all-day wear. While it provides lift, it may not match the support of an underwire bra for larger cup sizes like 38D.
- Does the bra have any visible seams that would show through a tight knit top, or is it completely seamless?
- The bra is designed with moulded cups and soft microfiber, making it smooth under T-shirts. It has minimal seams, such as at strap attachments and the band, but is not completely seamless.
