In my head, deep red looks gorgeous with navy, especially when the shades have a little metallic/frosted finish to them. To try out my theory, I picked up a couple of inexpensive shades from NYX:
This is Rust. Online, it looks much redder in the pictures, so I was quite disappointed when I opened the package and saw that it's actually more orange than red.
This is Frosted Ocean, a very pretty navy shade, but not as deep as the pictures show online. Online shopping can be very disappointing sometimes. But hey, I forged on and tried the combo
To start, I brushed Rust all over my primed lid. To brighten up the insides of my eyes, I used a shimmery white shadow (Zephyr from UD). Then I drew a v-shape along the outside of my eyes using Frosted ocean and an eyeliner brush. To finish, I ran a blending brush through the harsh edges.
