I bought these necklaces at ridiculously low prices today at my local Plato's Closet. The key necklace is Fossil and it was only $3! Of course, I can't pass up any ice cream themed jewellery so I had to get that awesome necklace as well. If you have a Plato's Closet in your area and you haven't checked it out yet, go do that!
I love necklaces because they're any easy way to pull an outfit together. Be creative and stack necklaces (although my necklaces usually get tangled up when I try that but maybe it will work for you!). Branch out a little bit in 2015 and buy some jewellery you wouldn't have bought in 2014!
