Designs that suit the ribcage
The ribs curve in two directions at once, which means flat, geometric designs can look distorted once they're on skin. Shapes with natural flow handle this better: floral stems, feathers, snakes, waves, script running vertically down the side, or a composition that tapers as it moves toward the waist. Vertical placement elongates the torso and reads well from the side; horizontal placement under the bust or along the lower ribs works for shorter phrases and small standalone motifs. Consider how the design behaves when you twist, bend or raise an arm — the ribs stretch and compress more than most placements, so anything reliant on perfect spacing between elements will shift.
