Buttercream Frills (or Ruffles) Cake

I needed a quick, sweet and feminine cake for my beautiful friend's b-day. I've seen the fondant frills but it seems to be a pretty time consuming process. So, I thought I could pull it off with buttercream...and I did!!! It took me only 30 min. or so to do the whole cake! I used the Ateco #104 tip.
