Word on the street is that Hologram nails are going to be hot again this Fall
and if you want to get in on the action, you've got to check out Layla Hologram Effect Nail Polish ($16 on Zappos.com)
Not only is the light-catching properties of this product incredible, but it wears well and didn't chip for a few days
(Also, top coat didn't appear to take away from the effect, which is great because a nice layer of that will make it last!)
I prefer Flash Black
but you can jazz it up with a color like Ocean Rush
Check it out!
