|Aww, there's even a cute guitar <3|
Now, after watching videos on YouTube and reading rave reviews on Sephora's website, I desperately want to go back to Sephora and try it on for myself (why I didn't do that at the time, I have no idea). I'm mostly interested in the silver (called "Glam Rock"--the names are quite cheesy) and opalescent pearl ("Distortion") colors, as they would probably look best layered over dark eye shadow.
After going back to Sephora, I found that I love this stuff! It was very sparkly and made quite a statement! I still couldn't spend the $18, though, but luckily I found a nice dupe at Hot Topic that's only $1.99. Yes, two dollars.
But if you have the kind of money to spend $18 on glitter liner (because the Urban Decay stuff IS better), have a look at this video review! She doesn't fit my aesthetic, of course, but she's very informative about the product and I liked listening to her talk. I didn't even turn off the video when she started rambling at the end, which was weird.
