Creating a floating crease requires three things: a good blending brush, pigmented eye shadow that doesn't fall, and a steady hand. (If you don't have the latter, you can always buy stencils, or clean it up afterwards with concealer.)
Rivera started with a subtle wash of the duo-chrome purple across the entire lids and then swept the lavender shimmer hue below the brow bones to create the crease. (The top two shades stacked on the right of the palette.) To accentuate the colour, he then used a thin dense brush to outline the crease with a fair-toned concealer, followed by a layer of the light then dark matte purple shades on top to intensify the shape.
In working with a shimmer and matte duo, he suggests you first lightly mist your eye shadow brush with a setting spray before applying the shadows to really lock in the colour. "That way you don't have to worry about any fallout," said Rivera. "Plus, when you're working with deeper skin tones, you have more propensity for contrast, so you want to get the colour really saturated and build up the shadow that way, so it doesn't look chalky."
