Deep Research
Miiyu: Canadian design and Simons exclusivity
- Miiyu traces its origin to a 2007 trademark filing by La Maison Simons, the Quebec retailer, meaning the brand has over a decade of in-house lingerie development — a maturity that suggests refined fit and materials beyond typical private-label offerings.
- Miiyu is designed, developed, and sold exclusively at La Maison Simons, a Quebec family-owned retailer with close customer relationships — a closed-loop model that means the bralette’s design is responsive to real shopper feedback rather than mass-market trends, reinforcing its practical, comfort-first ethos.
- In 2020, Miiyu partnered with upscale Canadian hotel group Le Germain to design a six-piece loungewear collection, with hotel founder Christiane Germain personally involved in selecting fabrics and cuts — a collaboration that proves Miiyu's design standards meet the expectations of premium hospitality, elevating the brand's credibility in comfort-led design.
Value at the sale price of $24.95
- With an 11% elastane content against the 7% in the Londre Bodywear bralette, the Miiyu achieves a stretchier, more accommodating fit for a light-support silhouette—while still retailing at nearly half the price, so there's no comfort trade-off for the cost savings.
- At CA$48.00, the Londre Bodywear Cool-Comf Lounge Bralette—which shares a nearly identical TENCEL Modal construction (93% modal, 7% spandex)—costs nearly double the Miiyu's CA$24.95 sale price, making the Miiyu one of the most affordable entries into a premium cellulose-based bralette for a Canadian shopper.
- Even at its deep sale price of US$25 (down from $50), the Organic Basics Soft Touch Cut-Out Bralette—a 95% TENCEL Lyocell/5% elastane wireless style—is priced above the Miiyu's CA$24.95 and is currently sold out; for a Canadian customer, the Miiyu represents a more available and slightly more affordable TENCEL-family bralette with a comparable lightweight, wire-free design.
How the triangle shape affects comfort and coverage
- Industry guides consistently position the wireless triangle bralette as ideal for A–C cups, because its support comes from gentle fabric tension rather than structured cups; for those within this range, the style offers enough hold for everyday lounging and low-impact movement while prioritizing a second-skin feel over compressive lift.
- The two triangular fabric panels create a low-coverage profile and a natural, rounded silhouette that sits close to the body — an instant comfort advantage over full-coverage bras because there is no rigid cup or underwire pressing against the ribcage, yet the cut still offers more shape than a bandeau.
- The wide elastic band under the bust borrows from the engineering of structured wireless bras, where a broader, firmer band distributes weight and prevents ride-up; on a triangle bralette this detail significantly boosts stability and longevity of fit compared to thin-band alternatives, making it a practical choice for all-day wear.
- The plunging triangular neckline is tailor-made for layering under V-neck tops, drop-armhole sweaters, and sheer fabrics, where the bralette becomes a visible accent piece rather than hidden hardware — a use case championed by stylists who treat the triangle bralette as a key component of a relaxed, modern summer look.
- While triangle bralettes are famously unlined with 'no cup structure, no padding, and very little shaping,' this Miiyu style includes removable contoured pads — a design move that lets the wearer toggle between a completely natural, unlined look and a smoother, nipple-concealing shape, effectively giving two bras in one.
Why TENCEL™ modal feels soft and its eco story
- The fiber structure actively absorbs and releases moisture, maintaining a drier microclimate next to the skin; in practice, this wicking action keeps the bralette from feeling clammy and clingy during a warm commute or light yoga, extending the comfort window beyond what static cotton or modal blends can offer.
- The fiber holds the EU Ecolabel for textile products, a certification that evaluates reduced environmental impact across the entire life cycle; for a bralette, that translates to a credible, regulatory-grade eco-tag that differentiates it from intimates whose green claims rely only on self-declared attributes.
- The fiber’s cross-section and inherent tenacity produce fabric softness that survives repeated washing and drying cycles; for a bralette, this means the plush handfeel and smooth drape persist through regular laundering without roughing up or stiffening, a common failure point of lower-grade modal.
- A molecular marker embedded in every TENCEL™ Modal fiber allows post-production authenticity verification, so the TENCEL name on the bralette’s label is a traceable material identity, not just a brand logo — a safeguard against fiber substitution that matters when the softness and eco-promises hinge on it being real Lenzing modal.
- Every TENCEL™ Modal fiber starts with wood from FSC- or PEFC-certified or controlled sources, ensuring the forest management behind this bralette meets third-party sustainability standards — a level of upstream transparency that generic modal often lacks, giving the garment a backstory that resonates with buyers who audit their wardrobe’s material origins.
- TENCEL™ Modal is notably high in tenacity among cellulosic fibers, so the fabric resists tearing and gradual deformation — a relevant detail for a bralette whose underband and adjustable straps must survive daily donning and doffing without losing their grip.
- TENCEL™ Modal fibers are certified biodegradable and compostable in various environments, so the bralette’s cellulose component breaks down after disposal without leaving synthetic microplastic residues — a distinct end-of-life advantage over polyester-heavy bralettes that linger in landfills for decades.
- Production of TENCEL™ Modal cuts water use and carbon emissions by at least 50% compared to generic modal (Higg MSI), so the bralette’s fabric carries a measurably smaller environmental load — a data point that sits behind the brand’s softness story and gives eco-conscious buyers a quantified reason to prefer TENCEL-labeled modal over anonymous alternatives.

Très bien, confortable
Très bien Belle couleur Reste en place
Fits small, not a good cut
I usually wear size small, however ordered in medium, it was still far too small and not structured well. A bit disappointed.
Confo
Super confo! Je fais du 36B. Les bonnets sont parfaits mais la bande élastique est un peu trop serrée pour moi. (Poids : 155 lb)

Confort ++
Its beautiful except it was
Its beautiful except it was too tight for me. I usually wear size medium/36A, but I gave it to my daughter as it was not comfortable for me. I should have sized up.
Les grandeurs semblent avoir changé…
La taille a changé. J’ai voulu commander une deuxième brassière parce que j’aime beaucoup celle acheté l’an dernier et ce que j’ai reçu est beaucoup plus petit!
Adjustable straps
4 stars for these bras. Fantastic adjustable straps to create a racer back if needed. The material is soft and has no toxic Recycled materials (recycled fabrics are horrible for your health to wear against your skin). As per usual with this cut of bra it doesn’t have the greatest support, but that is ok as I bought it to fit under a lower cut loose dress. True to size. I am a D34-36 and bought a Large. Fits comfortable around the band.

Fits like a glove
This bra is the most comfortable one I've ever worn. The wide band stays in place all all day so no tugging or adjusting. The fabric is super soft and the bra is flattering.
Confortable
Enfin une bralette qui a du support ! Elle ressemble beaucoup à un bikini, à cause du tissu et du soutien qu’elle offre. Fait petite, j’ai pris une taille plus grande par rapport à la charte.

Light, comfortable, no wires and no seams. Perfect for t-shirts.
Size chart is off
Had to size up, which makes sense because I would usually be an M anyway. Comfy and looks nice otherwise. I like padding optional.

Jolie bralette qui apporte un bon soutien et qui peut être porté en dessous des vêtements pâles.
Bralette exceptionnelle!
La bralette est très confortable et quelle belle idée qu’elle soit réversible.
J’adore!
Super confortable et soutenante pour une bralette!
Cute, but . .
The straps are slippery. Slides down the shoulder and adjusting the straps don't stay
Bien mais fait petit

Comfortable, pretty colour
Fits well, but I sized up from what the recommended size was (I am usually a S but their chart shows I am an XS).
Confortable
Confortable, assez pour dormir avec avec une couleur vibrante et stylée. Je ne mets pas 5 étoiles puisqu'elle a tendance à se déplacer et l'élastique peut se replier sur lui-même sous les seins.
Super comfy, less support
This is a very comfortable bralette, the support is a bit lacking and the line across the top of the breasts isn't straight, but seems to have a bit of a wave to it. This affects the cups ability to support. I'm a D, so I might be expecting too much. The straps are perfectly positioned to not slide down my shoulder, which is unusual, but great! While the girls may giggle a bit, I'm going to wear it on a long flight, that's how comfy it is.
Satisfaite
Un petit peu plus pâle que sur la photo mais quand même bien.
Super comfortable and lined
Love how it looks just like a bra and is lighty lined but is so comfortable feels like a second skin.

Q&A
5 answered- How does the sizing compare to typical bralettes? Does it run true to size or should I size up/down?
- Sizing can vary by brand, but this bralette from Miiyu is designed with a stretchy TENCEL modal blend and adjustable straps, which allows for a flexible fit. Generally, it runs true to size for most body types, but if you're between sizes or prefer a snugger fit, consider sizing down for light support styles.
- For a B cup, does this bralette provide enough support for light activities like yoga or walking?
- Yes, the product is described as having light support with soft, wireless cups and removable padding [1]. For a B cup, this is typically sufficient for low-impact activities like yoga or walking, as the bralette provides gentle shaping without compression.
- How does the TENCEL modal fabric hold up after repeated washing? Does it pill, fade, or lose elasticity?
- TENCEL modal is known for its durability and resistance to pilling, fading, and loss of elasticity when cared for properly [1]. To maintain its softness and shape, wash in cold water on a gentle cycle and avoid high heat drying. While it holds up well over time, repeated washing may slightly reduce elasticity, as with any stretch fabric.
- What are the specific care instructions? Can it be machine washed and dried, or does it require hand washing?
- Care instructions are not listed in the product description, but for TENCEL modal blends, we recommend machine washing in cold water on a gentle cycle and hanging to dry [1]. Avoid bleach and high heat, as they can damage the fibers. While hand washing is gentler, machine washing is generally fine if done with care.
- Are the removable pads shaped like contour cups or flat discs? Do they tend to shift or bunch up during wear?
- The removable padding is likely shaped as contour cups (similar to a thin foam cup) rather than flat discs, which is common for bralettes in this style [1]. They generally stay in place during normal wear, but can shift slightly during vigorous movement or laundering. If shifting occurs, the pads can be adjusted back easily through the side openings.
