Saisei, a minimalist-bent, quietly luxe activewear, intimates and loungewear brand has entered the market this week.
The brand’s debut assortment, the Foundation collection, was designed to celebrate the woman’s body through soft, fluid styles rather than change by restriction or reshaping it. It’s overarching inspiration is body language, notes Saisei creative director Simon Elmalem to WWD, and to “speak in a very quiet, intimate way — through the body.” The brand was founded to offer women timeless clothing that can take her throughout “the rhythm of the day,” spanning from sport to work to dinner to home.
“There’s a significant gap between luxury and premium that remains largely untouched. Luxury is aspirational, yes, but often inaccessible and logo-driven. Premium fashion is more affordable, but the quality can at times fall short, with the market being oversaturated with sameness,” Elmalem said. Saisei was designed to fit into that in-between space, with “fashion that feels elevated, well-crafted and emotionally resonant,” minus the luxury price tag.

The Foundations Collection is filled with chic and simple styles spanning from performance layers, including the 24/7 legging in ciclo nylon and recycled elastane, to seamless recycled nylon and recycled elastane intimates and ultra-soft loungewear in a calming palette rooted in earthy, natural tones. The line is available for purchase via the brand’s e-commerce platform, with prices ranging from $68 to $90 for bra tops and $88 to $140 for leggings and bottoms.
“Every piece in the collection begins with the fabric — thoughtfully developed to support both body and movement. We combine recycled fibers with performance innovation, crafting each garment using seamless technology that removes traditional stitching for a cleaner finish, softer feel and no binding friction points,” Elmalem explained.
Going forward, the brand will continue to evolve and “add what feels essential to staying true to a vision of thoughtful, lasting design.”
