I have a bit of a love/hate relationship with Sephora. I love that they created their own incantation of OPI for their in-house brand. I hate that they want me to pay $18 for a magnetic polish (hate more that I did). Right about in the middle are the Nails Inc polishes. At $11.50, they're pricey and for the most part, unexciting. However, they released a line of "3D Glitter" polishes (I'm still not sure what that means....) that are sparkly enough for me to overlook the price tag.
Bloomsbury Square is an absolute glitter bomb with purple micro glitter and pink hex glitter in a clear base. With a lot of these, they appear opaque in the bottle but when you apply them, hole city! This one was actually pretty good, building up a nice opacity with three coats. OMG IS IT SPARKLY ONCE YOU HAVE IT ON. So sparkly I think I'm still seeing glitter dots in my eyes.
I wasn't sure about the glitter combo in the bottle but on it merges together nicely. Both up close and further away, it's interesting which is good in my books.
The Verdict: I'm pretty sure you could reproduce a look like this for a lot cheaper than $11.50. If it was even $10 I'd say go for it as it really is super sparkly. For the price though, meh. It is pretty though.
