If you take a deep dive into my closet it doesn't go much further than brown, black, gray, and green. As the years have gone on and my style has changed, I've been much more of a neutral girl. I almost feel strange wearing a loud or bright color, mainly because I feel out of place. I'll sprinkle some "daring" colors in here or there, but stay pretty true to my color scheme.
If your color scheme is all black, only brights, or you wear blue everyday there is nothing wrong with that. Finding something that is true to you is a win in your book. I feel much more comfortable in my color palette of choice, I even feel more confident. And there is nothing wrong with a heavy dose of confidence. Everybody needs it.
P.S. this wall is to die for.
