Janira is the Spanish lingerie brand that’s perfected the art of everyday shapewear. Known for its ultra-comfortable briefs, smoothing slips, and seamless silhouettes, Janira delivers support without sacrificing softness. These are foundation pieces that work behind the scenes to enhance your natural shape, helping you feel smooth, confident, and held—in all the right places.

At The Foundation, we stock Janira’s best-loved styles. Whether you’re after a barely-there brief, light shaping shorts, or a smoothing camisole, Janira makes it easy to feel pulled-together under any outfit. Their fabrics are breathable, stretchy, and thoughtfully constructed for all-day wear.

If you’re looking for shapewear that feels like a second skin and actually stays put, Janira is the answer. It’s invisible under clothes, effortless to wear, and gives that quiet boost of confidence we all love.

What makes Janira different from other shapewear brands?

Janira strikes the perfect balance between comfort and control. Their fabrics are ultra-soft and flexible, but still offer effective smoothing and shaping. Unlike traditional shapewear, Janira doesn’t feel restrictive—it moves with you. Many styles are also seam-free or laser-cut, making them invisible under clothes. It's support you’ll forget you’re wearing (in the best way).

Are Janira briefs and slips good for everyday use?

Absolutely. Janira designs its pieces to be worn daily, not just for special occasions. The briefs are breathable and lightweight, and the slips and camis provide just the right amount of smoothing under dresses or workwear. They’re practical, wearable, and wash beautifully. If you’re building a reliable lingerie drawer, Janira deserves a spot.

Does Janira offer cotton options?

Yes, the Janira Cotton 100% range is one of their most popular. These styles combine soft, breathable cotton with a flattering fit that feels barely there. They’re ideal for sensitive skin or anyone who prefers natural fibres. You get comfort, hygiene, and subtle shaping in one. It’s everyday underwear done exceptionally well.

What’s special about the Janira Silkenya range?

The Silkenya range combines silky softness with light shaping and a totally seamless finish. These styles feel barely there but offer smooth coverage under clothes—perfect for every day or dressing up. If you're after invisible, second-skin comfort, Silkenya is a must-try.

How should I care for my Janira garments?

For best results, wash Janira pieces on a delicate cycle in cold water using a gentle detergent. Avoid fabric softeners and never tumble dry—lay flat or hang to dry to preserve elasticity. With a little care, these pieces will keep their shape and softness wear after wear. They’re designed to work hard and last long.

Is Janira true to size?

Janira runs fairly true to size, though some shaping styles have a snugger fit by design. If you're between sizes or prefer a looser feel, consider sizing up. Their size chart is reliable, and our team is always happy to help if you're unsure. Getting the right fit is key to that smooth, second-skin feel Janira is known for.

Janira shapewear and briefs—seamless, supportive and ultra-soft for everyday confidence. Spanish-made comfort that fits like a second skin.
