About SISU-the brand

SISU is elevated, fit-first womenswear designed for women in motion. Founded by Alisa Rose, SISU was created to serve an often-overlooked customer—women who live full, multidimensional lives and want clothing that moves with them, fits beautifully, and lasts beyond trends. Every SISU piece is intentionally built around Fabric, Form, and Function. We invest in premium stretch fabrics, precise fit, and thoughtful construction, so garments offer structure without restriction, polish without discomfort, and versatility across work, life, and travel. Functional details like pockets and adaptable silhouettes are standard, not optional. Designed and made in the USA, SISU delivers refined wardrobe staples with a modern edge—styles your customer will reach for repeatedly, season after season. Our collections are community-led. Through our Found(HERS) circle, our curated feedback circle of women, we receive ongoing insight into what women need now—and what’s missing in the current market. This results in relevant, wearable designs with strong sell-through and high customer loyalty. SISU is also deeply values-driven. Through our Infinity Initiative Fund, we reinvest in women by supporting entrepreneurship, wellness, and purpose-driven growth—values that resonate with today’s conscious consumer. Why boutiques choose SISU: • Fit-first design = lower returns • Underserved mid-size customer • Versatile, repeat-wear styles • Women-led, community-centered brandRead their story
