Mid-size isn’t in-between. It’s the center.


We’re here for the woman who’s never seen herself reflected in fashion’s extremes. Our pieces are intentionally engineered to fit mid-sized proportions—no size-scaling shortcuts, no compromise on comfort, no fast-fashion fluff. Just clothing that honors the way you live, lead, and move.

The SISU Difference

SISU was created for women who live in the often-overlooked mid-size range—sizes 8 to 16—and are ready for fashion that’s made with them in mind from the start. Unlike traditional brands that scale garments up or down from standard samples, we engineer every piece to fit mid-size proportions beautifully. With stretch-infused sustainable fabrics, functional details like hidden pockets and reversible styling, and silhouettes that move with you, SISU delivers style without compromise. Our designs flatter your shape, support your lifestyle, and offer the confidence of a wardrobe that finally gets it right.

Designed for your shape. Made for your movement.

Empowering Performance, Comfort Reimagined.

Polished enough for the office yet comfortable enough to wear in your free time
