Not only is it time to sell or donate the clothes you never wear or the pieces that are worn out or "out of style," it is time to re-evaluate who you are and who you want to be. Personally, I believe we should do this consistently as ideally your progression should be constant instead of scheduled. This is because if it is scheduled, it's probably not natural.
You are constantly changing so your look should constantly change as well. This doesn't mean that you can't continue to wear something that has been in your closet for 2 years. It means you should consider your lifestyle and get rid of whatever is no longer a part of it.
When you are consistently dressing for who you are and who you want to be, you've set your mind to be that person and people will view you in that way.
STYLE TIP: I don't even transition my closet from cold-weather clothing to warm-weather clothing for 2 reasons. !) If I have enough clothes in my closet to do that, I'm not living in style, I'm living in fashion. 2) I am able to style a lot of my warm-weather clothing with my cold-weather clothing.
