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.

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.
