What are the recommended washing and drying instructions to maintain softness and prevent shrinkage?

To maintain softness and prevent shrinkage, hand wash in cool water or machine wash on a gentle cycle in a lingerie bag, then air dry. Avoid bleach and fabric softener, as they can damage the TENCEL Modal fibers.

How does the fabric hold up after repeated washing—does it pill, fade, or lose elasticity?

Reviewers note the fabric stays soft and breathable after washing. The TENCEL Modal holds color well and resists fading. Pilling and elasticity loss are not commonly reported, but proper care (gentle washing, air drying) will help extend the garment's life.

Is the organic cotton GOTS certified and the TENCEL Modal sourced from sustainably managed forests?

The TENCEL Modal is responsibly sourced from sustainably managed forests, as noted in the product description. We do not have confirmation that the organic cotton is GOTS certified, but the product meets our Vision program standards for reduced-impact materials.

Product Insights

Miiyu's Stretch Ultra-Comfortable Brazilian Panty blends 47% organic cotton, 47% TENCEL Modal, and 6% spandex to deliver a soft, breathable feel with shape retention that prevents bagging, absorbing 11-13% moisture before feeling wet with 400-600 CFM breathability, maintaining durability and colorfastness when cared for properly by hand or machine gentle wash and air drying. At $12 each ($8 per pair in a 5-pack), it undercuts Gap organic cotton singles by $2.50, offering an affordable upgrade with the caveat that while TENCEL Modal is verified sustainably sourced, the organic cotton lacks third-party certification.

Deep Research

How the price stacks up against similar sustainable panties

At $39.95 for a 5-pack, each Miiyu pair costs about $8, only $1 more than Gap’s organic cotton hipster at $7 per pair in a 5-pack, yet adds 47% TENCEL Modal for a silkier texture — essentially a dollar-per-pair upgrade to a higher-grade fiber blend.
Priced individually at $12, the Miiyu panty undercuts Gap’s $14.50 organic cotton hipster by $2.50 while swapping pure cotton for a 47% organic cotton / 47% TENCEL Modal blend, giving the buyer better drape and moisture management at a lower cost.

How the organic cotton and TENCEL™ Modal blend feels and wears

The 47% organic cotton side opens up the knit to air permeability typical of cotton at 400–600 CFM, so the panty ventilates effectively and doesn't trap heat the way a predominantly modal or synthetic fabric can.
The 6% spandex content acts as a structural skeleton that keeps the elastic waistband and leg openings from bagging out, so the Brazilian silhouette stays snug after hours of wear and doesn't lose its shape wash after wash.
TENCEL modal absorbs 11–13% of its weight in moisture at equilibrium compared to cotton’s 7–8.5%, so the blend soaks up more perspiration before it feels wet, extending dry-comfort time on warm days.
TENCEL modal fibers are roughly 0.5 dtex—about 50% finer than standard cotton at 1.0–1.5 dtex—giving this jersey a conspicuously smooth, cool-to-the-touch hand that reads more like silk than a basic cotton panty.
