Janira Underwear

Janira sizing depends strongly on the collection. Most briefs use familiar S, M, L, XL and selected larger sizes, while Flexie Adapt includes highly elastic one-size pieces designed to adapt across several conventional sizes. Queen versions are separate patterns for larger size ranges rather than simply the same garment stretched further.

For everyday briefs, the waistband and leg openings should sit flat without rolling or cutting in. If a supposedly invisible edge is visibly stretched or feels tight, moving up a size or choosing a fuller pattern is usually better than expecting the fabric to relax permanently.

For shapewear, start with your normal clothing/brief size rather than deliberately sizing down for extra compression. A shaping brief should feel firm and controlled, but the waistband should remain in position and you should be able to sit and move comfortably. Stronger Perfect Curves and Silueta Forte styles provide more control by construction, not by being bought too small.

Janira does not revolve around cup-sized bras in the way many lingerie brands do, so the most important fit questions are usually rise, hip coverage, shaping level and whether you prefer a standard or adaptive one-size construction.

• Choose Esencial when you want simple, breathable cotton underwear for everyday wear.
• Choose Cotton Band when you want cotton comfort with a flatter, less visible finish across the back.
• Choose Best Comfort when softness, stretch and a stay-put invisible back are the main priorities.
• Choose Flexie Adapt when you want exceptionally elastic one-size underwear that follows ordinary body fluctuation.
• Choose Greta when you want Janira comfort with a more decorative floral-lace finish.
• Choose Secrets when you want an invisible back with selected shaping options through the front and waist.
• Choose Perfect Curves when you want genuine, stronger shapewear rather than simple smoothing.

Janira changes fibre blends according to the purpose of each collection. On current official product information, Cotton Band styles are listed as cotton and elastane, while Greta, Best Comfort, Flexie Adapt, Secrets and Perfect Curves are primarily polyamide and elastane. Selected soft-modal underwear combines modal and elastane, and some more decorative Cotton Band garments add polyamide lace to the cotton/elastane base.

Those choices are functional. Cotton provides a breathable, familiar everyday feel; polyamide allows a finer, smoother fabric with high durability; elastane provides stretch and recovery; and modal is used where a softer, fluid handfeel is the priority. Janira’s official pages do not publish fibre percentages consistently across every current style, so the exact composition should always be checked on the individual garment rather than assuming all pieces in a family are identical.

For everyday Janira briefs, a gentle 30°C wash is appropriate where the care label permits. Strong heat is the main enemy of elastic recovery: avoid tumble drying and radiators, and do not use bleach or harsh fabric treatments. Shapewear and delicate lace pieces benefit from gentler washing and being allowed to dry naturally without twisting.

We stock Soak lingerie wash, which is a useful gentle option for hand-washing Janira lace, invisible underwear and shapewear.
