If you've ever been on the hunt for underwear that actually fits your life—soft, supportive, no-show, and no fuss—welcome to our world. That's kinda why we created this company, you've found your people.
At iteration, we believe the humble thong deserves a glow-up. And our Mid-Rise Thong is the star: an everyday essential designed to feel like nothing, fit like everything, and move the way you do. It's a thong for people who love thongs, it's a thong for people who hate thongs.
Let's break down what makes it so good—and how to know if it's your new favorite.
Why the Mid-Rise Thong Deserves the Spotlight
- All comfort, zero compromise. This cut hits that sweet spot, sitting at your natural waistline (above a bikini, below a full brief), offering coverage where you want it, with none of the elastic dig or awkward lines.
- Seamless under anything. The minimal back means no VPL (visible panty line), and the mid-rise waistband stays flat and invisible under dresses, trousers, leggings—whatever the day calls for.
- Moves like you do. Life is not still. This thong flexes through your sit-stand-commute-repeat, your side stretches, your speed walks, and your naps: no ride-ups, no roll-downs, just resilience.
Comfort Starts With Materials That Matter
Your skin knows the difference. That's why we use TENCEL™ Modal, a fabric known for being:
- Insanely soft (like second skin)
- Breathable and moisture-wicking
- Gentle on sensitive skin
- Kinder to the planet – it's made from wood-based fibers in a low-impact process.
It's the fabric we reach for when we want our underwear to disappear—but still support us in all the right ways.
Why we LOVE TENCEL™ Modal
The fashion world is buzzing with talk of sustainability, but for us, it's a non-negotiable part of product design. That's why we make our Mid-Rise Thongs with ultra-soft, responsibly sourced TENCEL™ Modal. Let's break down what makes this fabric so special for the planet—and for you:
- Ultra-renewable origins that use 20x less water than cotton: TENCEL™ Modal is made from sustainably harvested beechwood forests in a closed-loop process, drastically cutting down on water use and chemical waste.
- Lasting softness you can feel good about: Known for its smooth, silky, ultra breathable texture, this fabric feels like a second skin—and holds up beautifully over time, wash after wash.
- Naturally breathable and odor resistant: Its unique fiber structure helps wick away moisture and regulate body temperature, keeping you fresh, dry, and comfortable throughout the day.
- It's 50% more absorbent than cotton. That means you'll feel dry longer even on super hot days
Comfort: The Little Details Matter
- The V-Front Waistband: We've all had our run-ins with stiff, rolling, or digging waistbands. We've thoughtfully engineered our signature V-front waistband to gently hug you without adding pressure, ensuring there's no awkward digging, muffin top, or unsightly marks at the end of the day.
- Flat seams & tag-free construction: We designed every seam to sit flat against your skin, and the bottoms are tag-free for a truly irritation-free experience—because the best underwear should be the one you forget you're even wearing.
- Resilient, lasting stretch: Thanks to a hint of elastane blended into the Modal, your thong maintains its shape wash after wash, staying comfortably supportive as you move.
How to Choose Your Perfect Mid-Rise Thong
- Check the rise. The waistband should sit just below your belly button, above any low-rise denim, but not as high as a retro brief. If it feels natural and supportive, you're on the right track.
- Fabric feel and stretch. Hold the thong to your wrist—does it feel soft and cool? Stretch and release; it should return to form quickly, with no bagginess.

Color your vibe: Our Mid-Rise Thong comes in a mix of soft neutrals and rich tones, like:
- Pink Sand – a barely-there pinky blush
- Sienna – warm and earthy burnt brick with pinkish tones
- Mahogany – rich, warm, and grounded
- Onyx – timeless, chic, and endlessly wearable
How to Style a Mid-Rise Thong for Real Life
- The 9-to-5 Essential: Pair it with tailored pants or pencil skirts—your coworkers will never know, and you’ll avoid panty lines from every angle.
- Gym-Ready Comfort: The flat seams and non-bulky cut mean you can confidently wear even under clingy leggings. TENCEL™ Modal’s moisture-wicking powers are a game-changer for active women on the move.
- Casual Days: Running errands or lounging at home? The gentle support and barely-there feel means this style is always a win—for binge-watching or dashing out the door alike.
Colors that Empower Your Everyday
Our customers love having options to both blend in and stand out. Which vibe matches your mood today
- Pink Sand: A soft blush that practically vanishes under lighter outfits and gives your underwear drawer a breath of fresh air.
- Sienna: Warm, earthy, modern—pairs beautifully with mid-range skin tones and autumnal palettes.
- Mahogany: A rich, deep hue for those days when you want a little depth and confidence or a beautiful neutral on mid to darker skin tones.
- Onyx: A timeless classic that never gets boring and is always chic. Black also works as a neutral base for darker skin tones.
Care Tips: Make Your Thongs Last (and Stay Soft!)
- Wash cold, hang dry. Gentle machine wash in a mesh bag will preserve the softness and stretch of TENCEL™ Modal. Avoid high heat, which can wear out elastic.
- Skip harsh detergents and bleach. Choose mild, eco-focused detergents that won’t strip the fabric’s natural softness or cause microplastic shedding.
- Rotate your drawer. Owning a few pairs makes each thong last longer and preserves their ‘just like new’ feel. This is extra important if you find you're always grabbing the same pair!!
Why TENCEL™ Modal Is Our Choice (and Might Be Yours, Too!)
- Eco-conscious from start to finish: Sourced from FSC-certified forests, processed in a closed-loop system, and made to last—a win for your skin and the earth.
- Breathe easy all day: Unlike synthetic blends, Modal allows air to flow, so you feel fresh from sunrise to bedtime.
- Kind to sensitive skin: Our undies are free from harmful finishes or dyes—just pure, wearable softness.
