Those are great tips and nicely outlined to help stay focused!
I do think it is very helpful to wear something "smart" and in a great color. That has helped remind me of where "the bar" is and that the grass may not be greener.
I like the wildcard idea too, in that sometimes there is a need NOT to just get more of the same, or at least to see what something actually looks like that I might not have considered.
I recently was in our local large dept store, not Nordie's, alas, but was reminded of its extensive amount and variety of clothing, along many price points, and including Theory, Nicole, EF, and others. I've been frustrated by online shopping busts and my preference for being able to try things on before buying, so may need to schedule a dept store day to just wander through the many areas for inspiration without commitment.
