I think you are showing a lot of mindfulness. Whenever one is trying to do less of one thing, I think you likely have to sub in something else. One thing that helps me not to just shop for the sake of it is to spend time on SYC and trying on some outfits. What's interesting is that this is also different from actually wearing your clothes and so is also a different type of pleasure, but has a similar "novelty" effect as shopping and the practical effect is that it actually results in my wearing more fun outfits than does more shopping! So after 30 minutes of SYC I can often set aside an outfit or 2 for the next day or a specific upcoming event, I feel good and I've spent no $$ and added no more stuff to my closet and may save time getting dressed as well. Everyone knows all about SYC to save $$, but for me I had to realize that I needed more deliberate outfit-making time because I had specific ways I wanted to look but did not have the imagination or confidence to just pull stuff down and have it work right off the bat. New clothes could never change that.
My mom sewed a lot and while I don't sew, we spent a lot of time picking out fabrics together and testing washability and other factors, and that helped me learn a lot about how fabrics and blends will behave. I use that when trying to decide on what level of "quality" is acceptable --apart from the initial fit, then the drape, wrinkling, and shrinkage or other behaviors of the fabric play a large role in how it's going to come across in the eyeball test of quality and in whether you'll get a reasonable return for the dollar. Also color--certain colors are more forgiving of "lower" quality though it's actually a combination of the color and the fabric and not always what you'd predict.
So if your Target pants are of a decent fabric, especially certain blends, they can work just great. Then sub time making some great outfits with them. The no-multiples-just-yet is a good compromise on filling a hole but not going overboard. You sound like you are making great progress.
