You have promised yourself forever and ever that you are going to clean out your closets and drawers but instead of moving forward, you just stuff more and more into the already stuffed closets. I know, it is a difficult project to undertake - weeding out the pieces you don't wear; it takes time and an open mind plus a whole bunch of resolve.
If you have way too much to sort at one time then I suggest that you decide to take it a foot by foot. Block off 12 inches in your closet and decide to really look at those few pieces in that short space. That is all you have to do at one time - 12 little inches.
If you LOVE it then put it in the "perfect for me" part of your closet. If you need to try it on, do it now. Does it fit? Good. Is the color fabulous on you? Good! Next question - do you wear it? If not, why not? It may be that the cut is just bad for your body shape or you need to add something to make it an outfit. Or maybe, just maybe you just don't like it even though you "should".
I think our closets are full of pieces that never make it onto our backs and out of the house. There is usually a good reason for the failure to actually wear 'that dress' or 'those slacks' or whatever but all too often, instead of moving it up and out, we choose to ignore it and shut the closet door.
