I love Wendy, she does amazing tutorials and her scarf video is something I watch all of the time. Having said that, it was her I turned to when I started hearing about color blocking and the summer trend to use it in style. What the heck is color blocking? Watch the video and find out. Wendy is so good at explaining, even I can understand it.
I also looked up a nice color wheel I'm going to print out and tape to my closet door for when I'm deciding what to wear.
