A chain reaction is a chemical reaction or other process in which the products themselves promote or spread the reaction. I think that pretty much sums it up. When I saw this shirt online, I knew that I HAD to have it. Plus, this skirt covers all the skirt trends this season: circle, leather, and pleated. And this Michael Kors bag is the absolute, best purse that I have ever owned (the straps can be worn 3 different ways)! So, unlike those ridiculously annoying chain emails…get on this chain reaction.
