Product Insights
The Xanthe Neon Trim Bralette offers a secure, comfortable fit through a tie-back closure that cinches to exact ribcage measurements, with scalloped edges and double knot preventing loosening during swimming. Its polyamide-spandex microfibre fabric delivers vivid initial neon color and a soft, 4-way stretch feel, but the vibrant trim fades gradually with chlorine and UV exposure—a tradeoff for color intensity versus durability. In-house Colombian production ensures consistent sizing, though wet microfibre may faintly reveal pad edges on light colorways, and proper hand washing and flat drying are required to maintain elasticity.

Deep Research
How the tie-back design affects fit and support
- The scalloped edging along the tie strings provides a subtle friction texture that helps the knot grip, reducing accidental slippage more effectively than smooth, flat strings — particularly useful for active swimmers who want the tie to stay put through surf or extended wear without needing to overtighten.
- A tie-back band cinches precisely to your exact ribcage measurement at any point along the strings, unlike clasp-band bikinis limited to the nearest hook-and-eye row — this means the Xanthe bralette accommodates weight fluctuations, menstrual bloating, or simply a preference for a tighter or looser band without compromising fit or requiring a new size.
- Because the back closure is a continuous string rather than a fixed elasticated band, there are no rigid edges or hooks to dig into the spine or ribcage — the microfibre fabric draws smoothly against the skin and the tie tension can be adjusted to avoid hotspots, making this bralette comfortable for lounging or all-day wear unlike many traditionally banded tops.
- Tying the back strings with a double knot instead of a bow significantly reduces the risk of the band loosening during vigorous swimming or beach sports — the flat profile of a well-tied square or double knot also sits more comfortably against the skin under your back than a bulky bow, and still unties easily post-swim.
How the microfibre handles chlorine and sun
- Because nylon absorbs acid dyes deeply, the tricolour neon trim reads as brilliantly saturated on day one, but chlorine and UV together break down those dye bonds; cold freshwater rinsing after every swim is the single most important habit to slow the inevitable softening of the neon over a full season of use.
- This 88% polyamide / 12% spandex microfibre is the standard premium recipe for fashion swimwear: nylon's soft, silk-like texture and superior acid-dye uptake produce rich, deep colors, while the 12% spandex is the moderate elastane content that delivers 4-way stretch without the rapid degradation that accompanies sky-high spandex levels, making the blend a deliberate balance of feel, fit, and practical durability.
Colombian swimwear manufacturing quality
- ONEONE operates as both a swimwear brand and an apparel production partner based in Colombia, with capabilities in pattern making, sampling, and private label swimwear manufacturing — so the Xanthe bralette comes from a company that directly controls its own production line, not from a disconnected contract factory.

Q&A
4 answered- What is the recommended cup size range for this bralette (e.g., A/B, B/C, or full bust)?
- This bralette is designed as a standard triangle bralette with soft cups and adjustable straps, typically fitting A to C cup sizes. For a more precise fit, we recommend checking the size chart or trying on in-store.
- After repeated exposure to chlorine or saltwater, does the neon trim fade or lose its brightness?
- Chlorine and saltwater can cause fading over time, especially with bright neon colors. To preserve the trim's vibrancy, rinse the bralette in cool fresh water immediately after swimming and avoid prolonged sun exposure while wet.
- Are the removable foam pads visible through the microfibre material when wet?
- The microfibre material is lightweight and may become slightly translucent when wet, which could make the foam padding edges faintly visible on lighter colors like Patterned White. The padding is removable if preferred.
- What is the best way to care for this bralette to prevent the microfibre fabric from pilling or losing elasticity?
- Hand wash in cold water with a mild, pH-neutral detergent, never bleach or fabric softener. Rinse immediately after each wear, gently press out water (do not wring), and lay flat to dry in the shade away from direct sun and heat.
