Pack of 3 microfiber tangas Discreet
Invisible knickers disappear under trousers, leggings or a fitted dress. Briefs, shorts, tangas, thongs or high-waisted styles: our invisible knickers for women come in cotton or microfibre, in sizes FR 34/36 to 54/56 (UK 6/8 to 26/28), in black, white or nude shades. To create a completely discreet outfit, also explore our invisible lingerie.
What are invisible knickers?
Invisible knickers are designed to leave no visible lines under your clothes. The fine fabric follows your skin, the edges lie flat and seams are kept to a minimum. The result: a second-skin feel with no trace under close-fitting fabrics. These are no VPL knickers, the pair you reach for to feel at ease from morning to night, whatever you wear.
Invisible knickers or seamless knickers: what is the difference?
Seamless knickers are one type of invisible knickers: they remove the seams, often at the sides, for extra discretion. But invisibility is not only about seams: fabric, colour and cut matter just as much. At Sans Complexe Paris, the Invisible Coton packs and the Perfect Curves briefs are seamless. The other styles rely on a fine, smooth microfibre.
Which invisible knickers should you choose for your outfit?
Under trousers or leggings
Stretched fabric reveals the slightest elastic. Choose a full-coverage cut that stays in place: the Unseen microfibre shorts, FR 38/40 to 50/52, or the Pure Invisibility medium-coverage briefs, M to XXL. If you like to cover the top of your thighs, the Pure Invisibility long-leg panty extends that second-skin feel.
Under a fitted dress or skirt
The higher the leg cut, the less visible the knickers. The Unseen microfibre tanga brief and the Discrète or Subtile packs are made for close-fitting cuts. For maximum discretion, the thong remains the lightest option, in microfibre or cotton.
Under a flowing dress or high-waisted jeans
The Perfect Curves high-waisted knickers rise to the waist, or even higher in the extra-high-waisted version. They gently smooth the tummy line and stop the elastic from sitting below your waistband. For firmer support, discover our invisible shapewear knickers.
Cotton or microfibre: which fabric for invisible knickers?
Cotton is soft, breathable and a favourite for everyday wear. Our Invisible Coton and Subtile packs prove it: cotton invisible knickers, comfortable from morning to night. Browse all our cotton lingerie to complete your drawer.
Microfibre is finer and smoother. It glides under close-fitting fabrics and dries quickly. It is the fabric of the Pure Invisibility, Unseen, Perfect Curves and Discrète lines. Your choice mainly depends on your outfit: cotton for everyday, microfibre for fitted clothes.
Nude, black or white: which colour stays invisible?
Surprisingly, white knickers show under white clothes. The most invisible shade is the one closest to your skin tone: nude knickers in blush, skin or beige disappear under light fabrics. Black remains ideal under dark outfits. For a discreet look from head to toe, pair your knickers with an invisible bra in the same shade.
Plus size invisible knickers, from FR 34/36 to 54/56
Invisible knickers must first fit you properly: too tight and they leave marks, too loose and they wrinkle. Our styles range from FR 34/36 to 54/56 (UK 6/8 to 26/28) depending on the line. Size FR 54/56 is available on the Perfect Curves extra-high-waisted knickers, and the Pure Invisibility line comes in M to XXL. To find your size, check our size guide for bottoms. If you are between two sizes, choose the larger one so the elastic does not dig in. Not sure? Book a personal advice appointment with our advisors.
Frequently asked questions about invisible knickers
What are invisible knickers?
They are knickers designed to leave no lines under your clothes, thanks to a fine fabric, flat edges and seams kept to a minimum.
What is the difference between invisible knickers and seamless knickers?
Seamless knickers remove the seams for extra discretion. Invisible knickers cover, more broadly, every style designed not to show, through its fabric, cut and colour.
Which knickers don't show under trousers or leggings?
Full-coverage microfibre shorts or briefs that stay in place without digging in. The Unseen shorts and the Pure Invisibility briefs are designed for this.
Which knicker colour is the most invisible under white clothes?
A shade close to your skin tone: nude, blush, skin or beige. White knickers, on the other hand, show under white clothes.
Cotton or microfibre: which fabric should you choose for invisible knickers?
Cotton for breathable everyday comfort, microfibre for maximum smoothness under fitted clothes.
Are there plus size invisible knickers?
Yes. Our invisible knickers range from FR 34/36 to 54/56 (UK 6/8 to 26/28) depending on the style, with a size guide to help you find yours.
Do high-waisted invisible knickers help smooth the tummy?
High-waisted knickers such as Perfect Curves gently smooth the tummy line. For firmer support, shapewear knickers are a better fit.
Can you wear invisible knickers every day?
Yes. In cotton or microfibre, they are designed for everyday comfort, from the office to the weekend.
How should you wash invisible knickers so they keep their shape?
Follow the care label, choose a delicate wash in a laundry bag and avoid the tumble dryer to preserve the fabric's stretch and smoothness.
