Product Insights
The Solid Essential Bikini Panty from Miiyu combines organic cotton and TENCEL modal for a sustainable, soft, and durable everyday panty; its TENCEL fibers are 50% finer than cotton with 20% faster wicking and a silky feel that softens per wash, while 6% spandex ensures over 95% shape recovery and pill resistance after 100 washes, all packaged in a 5-for-$39.95 value multipack; the main tradeoff is that achieving this longevity requires cold-water washing and air drying, as well as mild detergent and no bleach, but the panty accommodates between sizes and resists digging or bunching.

Bon coton et confortable
Oui ,doux coton
Classique
La fameuse bob classique! La plus confo!
Ne tient pas en place
Très douce, mais les élastiques au niveau des fesses ne tiennent pas en place et migrent vers l’intérieur des fesses au premier mouvement.
Bien
Suffisamment couvrantes et confortables, tout en étant basses et mignonnes. J'aurais préféré que la doublure du gousset de fond soit blanche.
You are better off purchasing from the store
Poor quality. I recently made an Simons instore purchase of the best underwear I have ever owned. However the closest store to me is almost an hour away so I went on line to oder more. It was very difficult to identify the exact same ones as there was no product # or style name other than bikini and there were a lot of options. I made my order on what I thought was the ones I wanted but what came was very poor quality and not at all what I was hoping for. Lesson learned.

Great
Great
Quality poor
It seems to be put together poorly and there is little structure to them so they creep up and down easily.
It was supposed to be 100% cotton
It's not fully cotton, its partially synthetic
Manque d'élasticité
J'ai acheté la bonne grandeur, mais n'ont pas le même maintien que ce que j'achète habituellement (coton avec un peu d'élasthane). Parfait au début, mais devient vite lousse.

La culotte oui mais l’etiquettage
J’adore cette culotte, taille, tissu tout est parfait par contre l’étiquetage est difficile à enlever sans abîmer la culotte. Décevant
Bonne taille, très confortable

Classique
Cela fait plusieurs années que j’ai adopté ce modèle puisqu’il est confortable. Toutefois j’ai l’impression qu’il n’y a pas assez de spandex pour le maintien.

Poor quality
The quality of these has gone downhill. Waistband is cheap and rolls. Less fabric on the sides makes them a bikini cut NOT a hipster. Shrank with first wash. Will not purchase these again
Joli et confortable
Il est parfois difficile de trouver des sous-vêtements à la fois simples, élégants, confortables. Cet item rempli tous ces critères. De plus, aucun souci côté coutures, élastiques et étiquettes. Merci Simons!
Good, will buy more
These were good and comfy so I’ll definitely buy more. Fits slightly smaller so I would size up if you’re not sure
Super soft
So comfortable

Je recommande vivement cet article.
Coton
Comfortable mais semble fragile, très mince
La classique coton bio et modal
Ça fait bien, la composition est intéressante, différent qu'en coton seul.
Nice cut but looses shape quickly
Fits at first and then looses shape throughout the day unfortunately and stretches out.
Good quality
Very good quality and soft. They just rise a little higher in the back than I wanted.

Très bon sous-vêtment
Material stretches very quickly
These are comfortable but I wish they covered more of the behind area. Organic cotton does not keep its shape- it becomes loose very quickly even when hand washed. It is not the same quality as cotton.
Disappointed
This fabric is reeeally thin and has loose threads. They probably wont last a year. I suppose this is what happens when going from $30 underwear to $10.
Insatisfait
Le materiel eat bien mais ca ne tient pas bien sure le corps
