Product Insights
Miiyu's Plain Microfibre Classic Brief offers an eco-friendly, hypoallergenic option in recycled nylon microfibre with a silky, smooth feel softer than cotton or modal, at a competitive price of $12.99 or $5.60 per unit in a 5-pack that buyers recommend. Designed in Canada to reduce import distance, it features a cotton gusset for sensitive skin but requires cold, gentle washing to prevent pilling, and its synthetic body is less breathable than all-cotton, potentially causing sweating. The secure, roll-resistant waistband and true-to-size fit adapt to body contours, and the line is also available in boyshort and lace-trim styles.

Deep Research
What the recycled nylon microfibre means for you
- The ultra-fine microfibre construction creates a smooth, silky surface that feels substantially softer and more luxurious against the skin than standard nylon or cotton knit underwear.
How it stacks up against other affordable sustainable briefs
- Miiyu is developed exclusively for Canadian retailer Simons and designed in Canada, a local-supply chain narrative that sets it apart from U.S.-based sustainable underwear brands like TomboyX and Subset, and offers Canadian consumers a lower-import-mile option without sacrificing eco-credentials.
- While the budget sustainable underwear segment is dominated by organic cotton brands like Pact (95% GOTS-certified organic cotton) and Subset (95% GOTS organic cotton/elastane), Miiyu's recycled nylon blend microfibre offers a synthetic alternative that diverts post-consumer waste—an approach that appeals to buyers whose primary environmental concern is ocean and landfill diversion rather than agricultural land use, and makes this brief one of the few recycled-synthetic options available for under $15.
- The recycled nylon microfibre fabric is also used across other Miiyu silhouettes like the boyshort and lace-trim classic brief, allowing a coordinated sustainable set—something few budget sustainable lines offer, as most concentrate on one or two cuts in their eco-fabric range.

Q&A
6 answered- How does the sizing run compared to other Miiyu underwear? Should I size up or down?
- We don't have specific size comparisons across Miiyu styles, but this brief is made from a soft, stretch recycled nylon blend microfibre with a stretch waistband, so it should fit true to size like most Miiyu underwear. Community feedback notes Miiyu runs true to size, so we recommend ordering your usual size.
- How does the recycled nylon fabric hold up after multiple washes? Does it pill or lose elasticity?
- The recycled nylon blend microfibre is designed to be soft and stretchy, and with proper care it should hold up well. Hand washing or machine washing on a cold, gentle cycle and line drying will help prevent pilling and maintain elasticity [1]. Community reviews describe Miiyu as soft and breathable, suggesting good durability.
- Is the cotton lining a full lining or just a gusset? What percentage of the brief is cotton?
- The cotton lining is a gusset, not a full lining. The product features specify "Lining: 100% cotton," and similar Miiyu styles list a "100% cotton gusset" [1], so only the crotch area is cotton — the rest of the brief is the recycled nylon blend microfibre.
- Does the stretch waistband stay in place during wear, or does it tend to roll down?
- The stretch waistband is designed to stay in place — it's a classic brief with a stretch waistband listed in the features. While we don't have specific customer feedback on rolling, microfibre briefs with stretch waistbands generally offer a secure fit without rolling when properly sized.
- Are these briefs suitable for people with sensitive skin or allergies? Is the recycled nylon free from common irritants?
- The recycled nylon fabric is generally hypoallergenic and the brief has a 100% cotton gusset, which can help reduce irritation. However, we don't have specific allergy or irritant certifications for this style. For sensitive skin, the soft microfibre and cotton gusset are typically gentle, but if you have specific allergies, we recommend checking the materials directly.
- Is the Miiyu line good quality for the price?
- Yes, users find it decent and pretty at 5 for $28.

Miiyu line recommended as affordable and pretty
I really love the Miiyu line from Simon's. Aerie is pretty good as well, and I often have surprisingly good luck at Marshall's/Winners

Miiyu cotton/modal blend praised for softness and breathability
I swear by the miiyu line at Simon's. Specifically the cotton/modal blend that gives a great blend of softness and breathability. They are usually in stock at the Simon's in Rideau Centre. They come in a range of cuts (bikini, hipster, thong, highrise) and colours. Here's the link to the hipster: https://m.simons.ca/en/women-underwear/panties/buy-more-save-more/organic-cotton-and-modal-hipster--11003-208714?colourId=28&catId=8402
