Product Insights
Miiyu's Stretch Ribbed Bikini Panty in TENCEL Modal offers a visual slimming effect from vertical ribs and a smooth fit without panty lines, using microfibers half the thickness of cotton that soften each wash, while the ribbed knit provides stretch recovery and breathability through air channels, though it retains slightly more moisture than cotton, reinforced with a cotton gusset for durability and priced at $12.99 or $7.99 in a 5-pack, a fraction of comparable designer modal styles.
Verified claims
- Softness
- Microfibers half the thickness of cotton create a smooth feel that grows softer with washing.
- Moisture management
- Absorbs 11–13% of its weight in moisture versus cotton’s 7–8.5%, and its ribbed air channels help it feel drier through the day.
- Durability
- Cotton lining reinforces washing durability; modal resists pilling.
- Visual slimming
- Vertical ribs create a visual slimming effect on hips and rear.
- Stretch recovery
- Ribbed knit stretches laterally and snaps back to prevent bagging.
- Breathability
- Rib weave improves airflow and moisture management.
- Fit
- Modal rib knit hugs body without visible panty lines.
- Price comparison
- At $12.99 (or $7.99 in 5-for-$39.95), costs 1/3 to 1/6 of a comparable $45 Calvin Klein modal bikini.
- Care
- Wash cold on gentle cycle, air dry flat, and avoid fabric softener for lasting softness.
- Sizing
- Runs true to standard US sizing; order your usual size.
- Fabric resilience
- TENCEL™ Modal fiber resists pilling, shrinking, and fading; fabric softens with each wash.
- Structural integrity
- Ribbed knit retains shape; cotton gusset provides wet strength for laundering.
- Sourcing
- TENCEL Modal is made with closed-loop production and fiber traceability.
- Value
- Reddit users describe the Miiyu line as good-quality, affordable underwear.
- Material
- TENCEL™ Modal offers durability, softens with wear, and uses closed-loop production.
- Sizing
- This panty runs true to size compared to standard US sizing; if you typically wear a medium, order a medium, though one buyer found the bikini cut ran large in the rear even when sizing down.

Everyday comfort underwear for casual daily wear
Reviewers describe this bikini panty as a go-to for casual everyday wear, with soft, silky Tencel™ Modal ribbed fabric that stretches without bagging. Multiple wearers report the fit stays put and feels comfortable and non-binding all day, without needing adjustments. Vibrant, beautiful colors are a nice touch for brightening up a basics drawer.[1]
For low-rise looks
Per an analysis of customer reviews, the bikini cut works under low-rise looks, while some reviewers preferred the brand's boy-short cut for fuller coverage. One reviewer noted the bikini cut can ride up during active days, though this was mentioned only once with low severity.[1]
Product comparison
Compared within this brand.
| Stretch Ribbed Bikini Panty Tencel™ Modal: Choose this if you want a soft, silky ribbed Tencel™ Modal bikini for casual everyday wear, in a low-rise cut that works under low-rise looks and is reported true to size with a stay-put, non-binding fit. Reviewers describe exceptionally soft, stretchy fabric that keeps its shape without bagging and comes in vibrant, cheerful colors. Note that some reviewers report the bikini cut can ride up during active days, with the brand's high-waist boy-short suggested as a more secure alternative.[1,2] | Solid Essential Bikini Panty Organic Cotton And Tencel™ Modal: Choose this for all-day, low-key wear: per an analysis of customer reviews, the organic cotton-modal blend feels cool and smooth against skin, and the soft, seamless low-rise bikini cut offers a flattering look without sacrificing comfort. Note the reported limitations: it is unreliable for running, HIIT, or other vigorous activity, with elastics that roll and fabric that creeps, and the ultra-thin material means lighter colors can be see-through. Reviews also say the spandex-free cotton runs small and stretches out permanently, so expect a sagging fit over time even if you size down.[3] | Stretch Essential Bikini Panty Organic Cotton And Tencel™ Modal: Choose this if you want a soft, stretchy bikini panty made of a jersey blend of organic cotton, TENCEL™ modal, and 6% spandex, with an elastic waist and curved, elastic-finished leg openings. It comes in five sizes from X-SMALL to X-LARGE and eleven colors, though the Black color is not listed in X-SMALL, so check your preferred size-color combination if you need that pairing.[4,5] |

doux
Le tissus est doux, extensible, les culottes restent bien en place toute la journée!
Parfait
Bonne taille confortable, belle couleur j’adore
Fit is awkwardly, too loose in rear
I liked the high waist boy shirt version of the underwear much better. It fits true to size, and doesn’t rid up. I found the bikini version was too big, even when going down in size. Love the fabric though, it’s soft & silky. Great nude if you are on the fair side.
Excellent
