I ordered this one at the same time as Gobsmacked. Trustafarian is another one of the new fall 2012 colors, and one of the two holographic polishes in the collection. The other holo is Dodgy Barnett, a silver/grey color that claims to be "highly holographic." I chose this one over Dodgy Barnett just because I have a ton of silver holos already, but not many sage green ones.
Butter London Trustafarian. This is a sage green, just not exactly the unique shade of sage I was expecting. Trustafarian is light, soft and dusty. It gives me severe lobster hands and is really very unflattering on my skintone. It has a scattered holographic finish with particles smaller than the Layla Hologram Effects, but larger than the China Glaze OMG holos. This is how it looks indoors.
Overall, not impressed. I love holos, but this particular shade of green looks awful on my skintone. I generally don't mind wearing unflattering colors as long as they're really awesome, but the holographic effect isn't strong enough to make up for the lobster hands it gives me. I think for now I'll stick with Layla Jade Groove for when I get the urge to wear a light green holo.
Butter London Trustafarian is available online and in-store at Ulta (which is where I ordered mine from). $14 for 0.4 oz.
