High-Tech Comfort
The "Alexandra" pink cotton seamless panties is the culmination of a quest: that of women's underwear you forget you're wearing. Designed to be invisible under your cotton or silk pajamas, this invisible brief offers a complete sense of freedom. It's the ideal companion for your nights, providing gentle support without any visible lines.
The Excellence of 150 Years of French Expertise
For this technical line, Sunday Sleep Club has partnered with a prestigious French manufacturer, an expert in corsetry and lingerie for over a century and a half.
Seamless Technology: a heat-bonded or laser-cut assembly (depending on the process) that eliminates traditional elastic and irritating seams.
Second Skin Effect: an ultra-stretchy and breathable fabric that hugs every movement without ever constricting.
Invisible Finish: it doesn't leave marks on the skin and remains undetectable, even under the most flowing garments like our Leandra cotton pyjama bottoms.
A soft and poetic powder pink for a feeling of infinite softness. This delicate shade blends naturally with the skin, bringing a subtle touch of femininity to the technicality of our Pima cotton and its relaxed gradation.

81% Pima Cotton 19% Elastane
Our fit philosophy: Relaxed grading
At Sunday Sleep Club, nightwear is an architecture dedicated to well-being. Our sets have been developed with intentionally generous and oversized patterns to accompany your movements with complete fluidity, without ever restricting the body.
• For a fluid and relaxed fit (Signature Style): Choose your usual size.
• For a more fitted or body-hugging look: We invite you to select one size down from your usual size.
For lingerie essentials, I enlisted the expertise of a French house renowned for its 150 years of savoir-faire.
Shorts, bralette, and tank top in the finest quality "Pima" cotton, with a touch of elastane for perfect comfort. No seams. Laser-cut edges.
For the bralette, the breast shape was molded into the fabric to avoid compression, ensuring absolute comfort.
This line was designed to be your sleep ally.
