After swatching them, I realized it looked a bit like Nina Out of the Blue, which reminded me of Chanel Blue Satin. So here they are together...please ignore a) the messy application and b) the weird positioning of everything because this was the best picture I got.
As you guys can see, they are all very similar. I will have to say though that the Chanel has a more vibrant/noticeable shimmer up close and in real life that didn't translate to the pictures. Here are Out of the Blue and Blue Satin by themselves:
All in all, if you're not crazy like me and don't need all three, I would pick the Nina one to own. Not only is it the cheapest option here (I think around $3 at Sallys? Compared to $6 for the SH and $19 for the Chanel), it's also easiest to find and once thinned the application and wear is pretty great. But, I will say that there is just something about the Chanel, a unknown WOW factor that just makes me love it. If it weren't so expensive I would buy more backups of the Chanel for sure. Good thing there are dupes!
PS: Has anyone been watching Shark Week on the Discovery Channel? I love it!
