Miiyu
High-Cut Essential Thong Organic Cotton
The Miiyu by Simons High-Cut Essential Thong is a women's underwear piece made from an ultra-soft organic cotton-blend jersey. It features an elastic waist and a high-cut design that sits high on the hip, with a narrow rear strap typical of a thong. Designed in Canada, this everyday thong offers breathable comfort for daily wear. Note: while a Reddit user recommends it as a 100% organic cotton option, the official description indicates a cotton blend, so verify the exact fiber content if 100% organic is required.

Product Insights
The Miiyu High-Cut Essential Thong Organic Cotton nearly eliminates panty lines and elongates legs with its high-cut leg and high-rise waist, but some buyers find the rise too present under tight clothing. It stays put during workouts and all-day wear without chafing or moisture buildup, thanks to buttery-soft organic cotton (93% cotton, 7% spandex) that reduces irritation. The 7% spandex prevents sagging, but cold washing and flat drying are required for durability (waistband lasts 6–12 months). Sizing varies by body shape, so reviews are more reliable than the size chart, and recent batches may have inconsistent fabric quality. At $10.99 CAD for a single pair or $39.95 for a 5-pack ($7.99 each), this exclusive designed-in-Canada line also offers environmental benefits by avoiding six carcinogenic pesticides and using up to 91% less water. However, seamless thongs provide more discretion, as some buyers report visible waistband and side elastic.

- Rise
Some buyers find the high rise feels too present under tight clothing.
Why this is supported

These are solid thongs in soft fabric + nice colours, I just wasn't a fan of the high-rise feel and prefer a seamless style
Customer review, April 2, 2025- Sizing
Sizing varies by body shape; rely on reviews, not the size chart.
Why this is supported
Reviewers are split among true-to-size, sizing down, and sizing up, with no dominant fit consensus, as the high-cut, high-waist cut interacts with individual hip-to-waist proportions.
Sizing is unpredictable: some recommend sizing down for a sleek fit, others size up to avoid snugness — consult recent reviews for your body type.
gotchaThis makes it essential to read recent reviews for your specific body type, as older reviews may not reflect current batch fit.
- Quality consistency
Recent batches may have different fabric quality, per a repeat buyer.
Why this is supported
Recent batches may have lower material quality — a repeat buyer who was happy last year says the fabric has changed and they're returning.
gotchaThis suggests that the fit may vary between production runs, adding uncertainty for first-time buyers.
- Comfort
Stays put: no chafing or moisture buildup during workouts and all-day wear.

A perfect thong.

Fun!
Great price for 100% cotton. Love the cut.
Good Organic Cotton Basic
The fabric is sturdy and comfortable, and although the elastic is narrow and firm, it is also comfortable. I am mostly happy with the product, although there are 3 things that are not ideal for me, thus the 4/5. 1) the cut is very very very high. It is a high cut thong, but for me I would prefer a not high cut thong, so it's true to name, but not my idea, which I chose for the fact that it's the only plain organic cotton thong available to me. 2) the printed label (so much better than a fabric tag!! thank you) unfortunately flakes off in the wash, leaving little dots of white here or there. 3) the gusset is only attached at one end, and I prefer when a gusset is attached fully. Personal preference!! Bottom line, there is nothing wrong with these thongs, and I am happy with my purchase, and can recommend them for someone who is looking for a high cut thong. I chose xs, 34" hips, 5'6", 110 lbs, and the fit is perfect, for reference.
Mes pref'
Beau coton, confortable et juste assez haute sur le ventre et la jambe pour un joli look. Je les ai essayé cet hiver et j'en ai recommandé 5 paires cet été. Ça en prendrait couleur chair :)
Good Thong!
Higher rise. Nice thin material doesn’t cling to clothes. . No show. Comfy.
Parfait
Discret
Impeccable!
J'ai acheté 5 couleurs différentes et elles sont toutes parfaites! Elles sont douces, confortables, le tissu semble de bonne qualité et j'aime qu'elles soient taille haute.
Good
I'm usually a medium or small. However these were a bit snug on me so you may want to size up, hahaha. I like this a lot.

Just right
Exactly the colour (pink) pictured, soft organic cotton, flattering high leg, and finally I've found a high-waist, just below the navel. I'm very pleased with my purchase and it makes me want to explore Simons other products. Highly recommended. Thanks.
Great thong if you like high-rise
These are solid thongs in soft fabric + nice colours, I just wasn't a fan of the high-rise feel and prefer a seamless style
