FAQ

Undershorts are soft, lightweight shorts designed to wear under skirts, dresses, or anything that needs a little extra coverage. Think of them as your secret weapon for comfort—no chafing, no riding up, no lines.

Nope. These aren’t about squeezing—they’re all about comfort. No compression, no digging, just a smooth fit you’ll actually want to wear, day after day.

Friction. When skin rubs against skin (or fabric) repeatedly, especially in heat or humidity, it can lead to irritation and that uncomfortable burning feeling. Undershorts act as a breathable barrier, so your thighs don’t have to suffer.

They’re perfect under skirts and dresses, but don’t stop there! Wear them under sheer fabrics, wide-leg pants, jumpsuits, or anywhere you want to skip chafing, sticking, or accidental flashing.

Totally up to you! They’re designed to be worn with or without underwear, depending on your preference. The gusset is breathable and smooth for all-day comfort either way.

    Transparent

    Ce short n’est pas fait pour être porté seul comme le mentionne la description. Le tissus n’est pas assez opaque et on peut voir à travers.

    Je suis fan!

    J'adore la sensation. Ça respire super bien, donc pas d'humidité qui reste, hyper confortable, plus jamais de cuisses en feu parce que ça frotte...seul mini pépin, parfois les shorts roulent lorsqu'on s'assoit.

    Haha oui ! Fini les acrobaties en mode sirène juste pour profiter du parc en robe :smile: On est trop contentes que la longueur et le confort soient au rendez-vous pour tes sorties plein air. C’est exactement le genre de vibe qu’on voulait créer : jolie, libre, et zéro prise de tête. Merci pour ton retour qui fait sourire.
