Echo is the suit RIOT is known for, and our most iconic silhouette for a reason.

The deep neckline, ruched waist, and high cut leg give you that long, sculpted shape that made Echo the one piece people come back for. It smooths, holds, and defines without making you feel restricted. The original minimal coverage keeps it sexy and intentional.

Wear it in the water or throw on jeans and keep going. Once you understand the fit, you understand why Echo became the suit that defined RIOT.

Designed for a sculpted, secure fit. This style runs true to size. We recommend selecting your usual size.

  • Ruched waist contours and accentuates your shape
  • Deep V neckline elongates the body
  • Minimal coverage throughout by design
  • High-cut leg lengthens the silhouette

Coverage Comparison

Echo Minimal Coverage
Minimal coverage throughout with a high-cut leg for an elongating silhouette. Designed for the woman who wears less with intention.

Echo Moderate Coverage
