This is a fun evening eye made up of several blues. Navy blue crease (The Body Shop Eye Shadow Single in #31), metallic seafoam-grey lids (Cyber Colors Cosmos Eyeshadow #01 Neptune), and a gorgeous matte prussian-blue liner (Stargazer Electric Blue Cake Liner - though it's not really electric blue) which costs all of £3.50.
The hardest item to obtain or duplicate would be Cyber Colors Cosmos Eyeshadow #01 Neptune (available at Sasa boutiques around Asia), which is a gloriously unique baked shadow made up of swirls of gunmetal, silver, and teal. I tried and tried but couldn't find any substitute. The closest would be to mix an iridescent teal shadow with a metallic grey.
Step 1: After applying a base, brush on a deep navy blue shadow in the outer V of the eye and smoke along the socket line (above the crease).
Step 2: As I was using an iridescent baked shadow, I used my finger to smooth on the lid color for maximum intensity. (Note that using your finger only works for baked/mineral shadows or very soft ones like Stila, and TheBalm, as they don't contain enough talc to get ruined and sealed over when they come into contact with oils in your finger.)
Step 3: Using a pencil brush, run the shadow along the lower lash line as well.
Step 4: The fun bit. Add a few drops of water or liner mixing medium onto a prussian blue cake liner and apply along the lower lash line and upper lash line, ending in an outer flick. (I highly recommend the Stargazer Electric Blue Cake Liner as it's a gorgeous and unique shade unlike any of the generic navies around.)
Step 5: Finish with mascara for the final look.
