Description

For a Firefly-inspired summer look, the aqua butterfly shapes and gold-edged white panels give this swimsuit-style costume its distinctive Star Rail silhouette. The central ornament and long hanging accents draw the eye toward the top, while the small aqua ruffles finish the hip line.

Dark detached sleeves contrast with the pale outfit; teal inner panels and white ruffled cuffs bring the color story down to the wrists. The upper back ties, leaving the back of the outfit open.

The coordinated look is photographed with a matching neck piece, headband and decorative accents. Pair it with your own pale wig to complete the character styling.
