About SISI

Fashion with a conscience, since 2019

SISI

Our Story

SISI was founded in 2019 in New York City by a small team of women who shared a simple belief: clothing should make you feel as good as it looks. Frustrated by fast fashion's quality issues and slow luxury's inaccessible prices, we set out to create a brand that bridges the gap โ€” timeless design, premium materials, and fair prices.

What started as a 3-person operation in a Brooklyn studio has grown into a beloved brand worn by over 50,000 women across the United States. But our mission hasn't changed: to create beautiful, sustainable, and accessible fashion for the modern woman.

Our Philosophy

We design with intention. Every piece in our collection is:

Our Promise

When you wear SISI, you're wearing more than clothing. You're wearing a commitment to quality, sustainability, and ethical production. We stand behind every piece we make โ€” if you're not satisfied, we'll make it right.
