I am sure you are looking for some special color for the summer, something shining, unique and vivid. Chanel 531 is a very special green mental color. It you want to try something really different and little bit crazy, this a good choice!
Apply once. I am not sure if every one could accept this color, but actually this is not so bad, and it is beautiful as long as you think it is.
Apply twice, A more intense and mental feeling, The texture is kindly of silly, so you do not need to worry if the color is so bright.
