I'm such a sucker for nude/gold holo polishes lately, and I was lucky enough recently to get OPI DS Design at an incredible price!
OPI - DS Design
Design is a perfect nude base with tons of sparkly holo pigment, just like the others in the DS series. For some reason, the rainbow colors seem a bit more subdued in this one, but it's still very stunning in the sun. In the shade, it matches my skin tone PERFECTLY.
Unfortunately, DS Design is discontinued (along with all the other holo DS polishes) and can be tricky to find. I found mine in a blog sale, so keep your eye out and you might just get lucky!
