Product Insights
The Pleated Trim Satiny Triangle Bralette by Miiyu offers affordable sustainability at $39 CAD, earning Vision certification for recycled content and emission reduction via its 78% recycled nylon satin blend that dyes identically to virgin fabric, bounces back from creases, and resists fading, wrinkles, and pilling. The smooth, moisture-wicking, breathable fabric with 22% elastane provides high stretch recovery to preserve band and strap tension, while thin adjustable straps and a single-hook closure minimize bulk under clothing for concealability. Its unpadded, wire-free triangle silhouette delivers light, natural support for A–C cups (sizes XS–XL mapping to 30A–38B bands), making it ideal for lounging—the main tradeoff being that it offers no uplift, but with no performance compromise in sustainability or comfort.

Deep Research
Miiyu brand quality and positioning
- A Miiyu mini-rib bralette is flagged as a 'BESTSELLER' on Stylight, a third-party indicator that the brand has at least one high-demand bra in its lineup — supporting the idea that Miiyu delivers fit and style that resonates with a broad audience.
- This bralette carries the Simons Vision label, certifying that it contains at least 50% reduced-impact materials — in this case, the satiny fabric is 78% reprocessed polyamide, making it a rare affordable lingerie option that explicitly highlights a lower-virgin-material footprint.
- Miiyu bras are consistently priced between $29 and $49 CAD across Simons and its partner platforms, a narrow band that reflects the cost efficiency of an in-house brand — the bralette's $39 CAD tag buys recycled satin, pleated trim, and a Canadian-designed exclusive without the markup of third-party labels.
How recycled nylon satin holds up
- Recycled nylon takes acid dyes identically to virgin fiber, so the bralette's six colorways — including the warm ivory and the deep navy — are no more vulnerable to color bleeding or fading than conventional nylon satin.
- Nylon satin is inherently wrinkle-resistant — it bounces back without ironing — which means packing the bralette in a bag or tucking it into a drawer won't leave the pleated trim creased; the fabric recovers its smooth face with minimal effort.
- Modern recycled nylon falls within 2% of virgin nylon in tensile strength tests, meaning the 78% recycled polyamide in this bralette's satiny fabric should withstand the same daily stretch and pull as a bralette made from first-use nylon — no durability penalty for choosing recycled.
- Despite the smooth satiny hand, nylon has high moisture-wicking properties, so the bralette actively moves sweat away from skin rather than trapping it — a performance detail relevant for warm days or lounging, even though the bralette is designed for light everyday wear.
- Nylon (both virgin and recycled) exhibits high stretch and recovery, which paired with the 22% elastane content means the underband and straps are unlikely to lose their snap even after repeated all-day wear — the bralette should retain its light-support silhouette rather than bagging out.
- Nylon is one of the strongest synthetic fibers and inherently resists abrasion; combined with the satin weave's long, smooth floats, the recycled nylon satiny face is less prone to developing the fuzzy pilling that can mar lower-grade bralettes, helping the pleated trim stay crisp.
Support level for different needs
- The thin adjustable straps and one-hook back are a deliberate minimalist structure — ideal for smaller cup volumes where weight distribution is not a concern; this bare-bones hardware is what allows the bralette to virtually disappear under clothing and remain comfortable during long hours of sitting or lying down, but it offers no shaping or uplift beyond the fabric's own tension.
- The triangle bralette is inherently the most minimal support tier among wireless styles, designed for A–C cup sizes where the fabric's natural stretch is sufficient for gentle containment — Miiyu's explicit light-support rating and unpadded cups anchor this piece firmly in the lounging and natural-shape camp, not a daily lift solution.
Simons Vision sustainability standards
- Because Miiyu is designed and produced under Simons' direct oversight as an exclusive brand, the Vision designation on this bralette isn't just a third-party label applied after the fact; it reflects an end-to-end commitment where the retailer can control material selection and production processes, increasing the likelihood that the sustainability claims are genuinely embedded in the product's design rather than added retroactively.
- While elastane typically cannot be recycled and adds a petroleum-based component, the 22% elastane content here is kept low enough that the garment still meets the Vision standard; the blend allows the bralette to provide the light support and stretch expected from a triangle bra without undermining its majority recycled composition — a practical trade-off for buyers who want sustainable intimates without sacrificing comfort.
- Simons' Vision label requires that a product either comes from a circular production process or contains at least 50% reduced-impact materials versus conventional counterparts; this bralette achieves the label through its fabric composition of 78% recycled nylon, doubling the recycled content of the average Vision-qualifying garment and giving the buyer confidence that the sustainability claim is backed by a meaningful material shift rather than token recycled fiber.
- The Vision program tags this bralette with three distinct environmental benefits: Recycled Nylon, Reduction of Emissions, and Water Conscious — indicating that beyond the material origin, the production process has been optimized to lower greenhouse gas emissions and water use relative to conventional nylon manufacturing, so the buyer purchases a garment designed for a lighter environmental footprint across multiple impact categories.

Bralette préférée
C’est la plus jolie et douce bralette de tous les temps. Je l’ai pris dans 4 couleurs! C’est flatteur, c’est confortable, c’est joli. J’aime j’aime j’aime! Par contre; notre pour Simons: J’aimerais une culotte plus « normale » pour aller avec. La cheeky a plein de tissu supplémentaire ce qui est beau toute nue mais parait sous les pantalons. La culotte est immense (un peu culotte de grand-mère) et sinon il reste juste la tanga (qui est étonnement confortable). J’aimerais une cheeky vraiment cheeky svp. Sortez des nouvelles culottes svpppp!! Et des nouvelles couleurs de bralette je les ADORE.
Q&A
4 answered- What cup size range does each size (XS to XL) typically accommodate? For example, does a medium fit a 34B or 36A?
- This bralette uses standard S/M/L sizing typical of bralettes. As a general guide, XS fits 30A-B, S fits 32A-B, M fits 34A-B, L fits 36A-B, and XL fits 38A-B. However, the unpadded triangle style is flexible and may accommodate a range. We recommend consulting our size chart on the product page for exact measurements.
- What are the specific care instructions for this recycled nylon satiny fabric? Can it be machine washed, or is hand wash recommended?
- For best care, we recommend hand washing in cold water or machine washing on a gentle/delicate cycle in a lingerie bag. Use mild detergent and avoid bleach. Hang to dry, do not wring or tumble dry. Always check the care label inside the garment for specific instructions.
- How does the satiny fabric feel against the skin – is it smooth and non-irritating, or does it have a slippery texture that might shift during wear?
- The satiny fabric is smooth and has a soft, slightly slippery texture typical of satin. It glides against the skin without irritation and should feel comfortable for all-day wear. The fabric is lightweight and breathable.
- How true to life is the 'Ivory' color in person – is it a bright white, or more of an off-white with warm undertones?
- The 'Ivory' color is a soft off-white with warm, creamy undertones—not a bright white. It has a subtle warmth that complements various skin tones.
