OPI DS Extravagance. A rich plum purple with slight holographic effect. See that glowy holo on my pinkie? This is how the polish glows under the sun. My camera couldn't pick it up.
You can see the holo effect here
Here's an old photo of Coronation from the same collection:
OPI DS Coronation. It's a silver with a scattered holographic effect. It was opaque in 3-coats. This was the longest wearing manicure I've worn. I wore this for 8 days! I got sick. Luckily, I had sparkily nails to keep me entertained.
You can see the holo shift here.
Though these holos are not as linear as the China Glaze OMGs or the Layla holographics, these are still really nice colors. Some holographics dull under artificial lighthing and become rather drab. These OPIs remain shimmery and glowy under regular lighting which I like.
I was able to find these in a couple of different beauty shops that sold OPI. I think they can found online for relatively reasonable prices. Unfortunately, the most recent Designer Series release was not holographic.
Thanks for reading!
