I have been keeping a Fall/Winter 2005 folder under My Pictures which I save pictures of things I am wanting to buy. For the picture name I include store, item, price (example:vsbouclecardigan49). I sometimes look at those pictures, and when an item doesn't seem so great anymore, I delete it, narrowing down my list.
I am so picky, and since I don't have lots of money to spend, I have to look EVERYWHERE just to find something suitable in my budget.
This season I have been keeping in mind what I already own, and buying things that will coordinate well with the other stuff. This strategy is working very well.
