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.
Verified claims
- Exclusive design
- Miiyu is Simons' house brand, designed in Canada and sold only at Simons.
- Value
- At $10.99 or $7.99 in bundle, undercuts $14.50 Gap organic.
- Gusset
- 100% organic cotton gusset meets gynecologist-recommended standard.
- Fit
- The jersey knit provides built-in 2–4% widthwise stretch without elastane, and the thin flat elastic at the waist and leg openings grips gently without digging.
- Competitive pricing
- 5-pack at $7.99/pair saves 27% vs single and undercuts premium organic brands by 45-75%
- Shrinkage
- This 100% organic cotton jersey can shrink 1–5% in the first wash; cold water and air drying hold that shrinkage to a minimum.
- Pilling
- Mesh bag and gentle cycle reduce pilling; pills shed naturally.
- Care
- Air drying preserves the elastic edging's stretch and fit.
- Detergent
- Use pH-neutral, bleach-free detergent for lasting softness and color.
- Vision program badge
- Simons' Vision program badge certifies reduced-impact via 100% organic cotton, annotated water-conscious and emission-reduction.
- Gusset
- The entire panty is 100% organic cotton, so the gusset is all cotton by default and meets the widely cited recommendation that the crotch liner be all cotton.
- Sizing
- Some buyers report these panties run large; one reviewer who is 5'7" and 125 lbs and usually buys small would have chosen extra small, and other reviews describe the fit as generous.
- Breathability
- The 100% organic cotton jersey is naturally porous, allowing continuous air circulation that pulls heat away from the body and reduces the risk of irritation from synthetic fibers.

Everyday wear and all-day lounging in breathable organic cotton
Reviewers describe this bikini panty as a comfortable pick for daily wear, lounging, and work-from-home days, with soft, thin, breathable organic cotton that feels natural. The fit earns repeat purchases when the size is right, though sizing runs large — especially in the hip — which can cause bunching, and a loose fit may let the waist and leg elastic shift out of place. Some also note the fabric is semi-sheer.[2]
A sustainable-fashion pick for organic cotton underwear, with durability caveats
Shoppers motivated by sustainable fashion are drawn to this bikini panty for its 100% organic cotton composition. Customer reviews are mixed, however: some report thin material and construction issues like loose threads or holes after one wear, which may shorten its lifespan.[2]
Product comparison
Compared within this brand.
| Plain Edging Bikini Panty 100% Organic Cotton: Choose this for everyday low-rise bikini coverage in 100% organic cotton jersey — a thin, soft, breathable knit with full back coverage and plain elastic edging that reviewers say is comfortable for all-day wear when sized correctly. Note that sizing runs large (especially at the hip), so consider sizing down, and be aware of reported batch-to-batch fit variability and inconsistent quality such as loose threads or holes. If you are fragrance-sensitive, reviews describe a strong chemical odor on arrival that washing may not fully remove, which has triggered migraines for at least one customer.[1,2,3,4] | Scalloped Edge Bikini Panty Organic Cotton: Choose this if you want a lightweight, tag-free bikini panty in soft, breathable organic cotton for everyday wear, sleepwear, or under form-fitting outfits like yoga pants and slim dresses, where reviewers report it stays invisible thanks to a smooth, no-roll waist and flat scalloped lace edges. Be aware that sizing is hit-or-miss — many find it true-to-size, but some report wedgies, bagginess, or stretching during wear because the thin, low-recovery fabric shifts on curvier figures. The scalloped lace edge can also irritate seam-sensitive wearers during extended sitting, and air-drying is recommended to help maintain the shape.[5] | Lace-Waist Bikini Panty Organic Cotton: Choose this if you want a cotton-forward everyday bikini panty with a decorative touch: the body is a 93% organic cotton, 7% spandex knit with an elastic waist trimmed in scalloped floral lace and a small satin bow at the center front. The moderate-rise bikini cut has a full-coverage back panel, and it comes in sizes X-Small to X-Large with a wide color range from Black, White, and Grey to prints like Polka Dot and Heart. Note the waist lace is slightly sheer compared with the main fabric, per the product imagery.[6,7,8] |

Thin, comfy all organic. Exactly
Thin, comfy all organic. Exactly what I wanted
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
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.
Fait très grand.
Élastique trop large et apparent. Cependant, les couleurs mauve et vert sont wow.
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)
Just what I ordered
Haven’t worn them yet
Hole during first use!
Fit well, cute, but one of the 5 got a hole on the first wear.
Belle culotte pur coton un

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.
doux et confortable
excellent achat
Light organic and best part no spandex
Purchased before and still thrilled
Ni plus ni moins
Je m'attendais qu'ils soient plus épais. Ont voit au travers de la matière. . .
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.
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
Nice service
I'm completely sitisfiyed by the service. Best recommendations!
Super panty briefs

Best underwear I've ever worn
I think I've bought 10 pairs now! This underwear is 100% cotton and fits beautifully. I hope you never stop making it!
Très confortable
J’aime beaucoup, je trouve par contre que l’élastique au fessier pourrait être plus raide afin qu’il reste plus en place.

J’adore! Coton biologique essentiellement

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
