Product Insights
Miiyu's Hydra Ribbed Plunge Bra combines a deep plunge with a smooth T-shirt fit, using a moisture-wicking modal blend that absorbs 50% more moisture than cotton, retains shape with 95% recovery after 10k stretch cycles, and offers four strap configurations (standard, racerback, halter, one-shoulder) with fixed cups that eliminate shifting. Designed in Canada as a Simons house brand, it undercuts Calvin Klein and Simone Pérèle by 30–80% at $49 regular or $19.99 sale, though its subtle ribbed texture may show under thin fabrics.
