Oh, the stacking rings. It seems like they are everywhere, on blogs, Pinterest, in magazines and fashion editorials. Despite the fact they are all over the place, it's hard to find ones that go well with your style and look good. 
Also, if you buy two sets of different rings it might be tricky to combine them. I have two sets, from H&M and Asos. They can be mixed, because rings are the same colour. If you are looking for cute stacking rings these are a good option. Before you start wearing them, try to stack them in different ways to  see which one looks the best.
