I promised to do this comparison a few days ago and I apologise it took me so long (and I also do not have Thunderbird which was asked for). I compared three beautiful shades from China Glaze: Long Kiss (LK), Mommy Kissing Santa (MKS) and Short & Sassy (SS). All of them are easy to apply, have the standard China Glaze formula and all covered in two coats. No dupes here so it is up to you which shade you prefer. I am glad I have all of them but looking at this picture I love the depth of Short & Sassy. What do you think? I wish you a great weekend!
