I can't really say this is a new trend. It's been around for about two years, but I've been seeing a lot more of it recently, as more brands have jumped on the bandwagon. Colour changing or mood nail polishes are just about everywhere these days!
Now when I was a pre-teen, mood rings were all the rage. And as trends go, they return very often. This one has just been revamped a little, but the basics are still the same. The nail polish changes colour according to temperature, but what's really cool is that the nail edge is often a different colour than the rest of the nail, because it's cooler there.
Here are some examples. (None of these images belong to me, I found them all on Pinterest.)
This is the perfect trend for spring and summer, because your nails will actually enjoy the ocean's waves or the pool right along with you. :P
What do you think? Would you wear it? Lemme know!
Stay beautiful and be kind to animals,
