This product is a low-rise bikini panty made from 100% organic cotton jersey, designed in Canada as part of the exclusive Miiyu line at Simons.

Product Insights
Miiyu’s Plain Edging Bikini Panty is an exclusive Simons design made from 100% organic cotton, offering a core promise of affordability at $10.99 or $7.99 in a 5-pack, undercutting premium organic brands by 45–75%. Its flat elastic edging provides a no-dig hold, while the 100% organic cotton gusset meets gynecologist-recommended standards. Sustainability is validated by Simons Vision badges for Water Conscious and Emissions Reduction. The main tradeoff is that maintaining fit and minimizing shrinkage and pilling requires careful care: cold water wash, mesh bag, gentle cycle, air drying, and pH-neutral bleach-free detergent. Reddit users on r/FrugalFemaleFashionCA endorse it as a go-to for affordable organic underwear, noting it competes with Aerie.

Because the entire panty is that material, the gusset meets the recommendation. The organic cotton is free from synthetic residues. Its jersey construction provides natural stretch without elastane—unlike blends such as Gap's (

- Shrinkage
Cold water and air drying minimize shrinkage.
Why this is supported
For 100% organic cotton jersey, cold water is critical to avoid thermal shock that causes fiber contraction. As one source advises,
✅ Wash in cold or lukewarm water (below 30°C/86°F)
tarbo.comExperts note that
This means a slight shrinkage of about 1–5% after the first wash is normal.
tarbo.comAir drying further reduces contraction, keeping the panty fitting as intended.
- Pilling
Mesh bag and gentle cycle reduce pilling; pills shed naturally.
Why this is supported
To reduce surface pilling, a laundry bag is recommended:
Use laundry bags.
pinkclubwear.comand
✅ Use gentle or delicate wash cycles (or hand wash when possible)
tarbo.comBecause cotton is a natural fiber, any pills that form are weak:
If fiber strength is low enough, pills will naturally shed.
unitexunderwear.comThis means the fabric stays smooth without needing a fabric shaver.
- Care
Air drying preserves the elastic edging's stretch and fit.
Why this is supported
The thin elastic edging on waist and legs is vulnerable to heat damage. As a source explains,
air drying instead of tumble drying prevents the elastic from stiffening and losing its recovery stretch
Wash durability and long-term care — elastic_preserving_air_dryThis ensures a snug but gentle hold for the panty's entire lifespan.
- Detergent
Use pH-neutral, bleach-free detergent for lasting softness and color.
Why this is supported
To prevent chemical breakdown of organic cotton fibers, the detergent choice matters. Verified advice:
✅ Choose mild, pH-neutral detergents—avoid bleach or enzymes
tarbo.comThis slows fiber degradation and maintains the fabric's soft feel and dye vibrancy.
- Vision program badge
Simons' Vision program badge certifies reduced-impact via 100% organic cotton, annotated water-conscious and emission-reduction.
Why this is supported
Simons' Vision program requires a product to either originate from a circular production process or contain at least 50% reduced‑impact materials compared to conventional counterparts;
this bikini qualifies through its 100% organic cotton, which avoids synthetic pesticides and fertilizers, and the badge is further annotated with 'Water Conscious' and 'Reduction of Emissions' to highlight specifically managed impact areas in the cotton's cultivation and processing.
Sustainability certifications and production ethics — vision_program_badgeThis explicit statement of the criteria met makes the sustainability credentials transparent and easy for shoppers to verify.

Ni plus ni moins
Je m'attendais qu'ils soient plus épais. Ont voit au travers de la matière. . .
Good
Love how they are 100% organic cotton. They are tall undies, and the sizing was too big. I needed to wash and dry to shrink a bit, so don’t know how long that will last. I’m 5’7” 125 lbs. Bought small, but would have bought extra small. (I have small hips)
Le bikini bords unis Pur coton biologique
J'ai acheté quelques paires de ces culottes en janvier et en septembre 2025. Celles que j'ai recu en janvier 2026 étaient de même taille, mais en réalité, elles étaient un peu plus grandes.
Light organic and best part no spandex
Purchased before and still thrilled

Confort
Petite culotte confortable, bonne élasticité et de couleur acceptable. Un seul bémol, sa composition en coton biologique ne surpassera jamais le tout coton naturel. Mais environnement oblige.
Hole during first use!
Fit well, cute, but one of the 5 got a hole on the first wear.
Low Cut Waist
Really like the material and coverage of these but I find the style to be a bit too low cut on the waist
Seams left with threads loose on every pair
I ordered 5 pairs of these and every pair has loose threads on multiple seams. I expected a slightly higher quality from Simon’s, especially since they are 100% cotton
Disappointed
I'm disappointed in these underwear. The fabric is very thin and feels like it won't last very long. The size or cut seems strange. It's either too big or the cut is very high at the back. I end up with fabric bunching. I bought 6 but will be returning the 5 I haven't worn.

Women's undies absolutely reeked of MEN's cologne/body spray
These women's undies (and the other things I ordered, but especially these) came reeking of men's cologne or body spray, giving me a 3 day migraine, and I had to return them along with everything else I ordered, without being able to get replacements. WHY were women's undies from the warehouse saturated in men's fragrance? Super disappointing, will not order from SIMONS again. ps Forcing me to say how things fit when I can't be near them makes no sense
Nice service
I'm completely sitisfiyed by the service. Best recommendations!
