WOW. You've completed your shopping for the entire year (except for a few remaining wants should you find them). I can only say congratulations to you and bow before you. I'm done shopping for the season (not year). Like you, I am not calling it a fast, but there should be little I need going into Summer. I want to actually wear my clothing and enjoy them.
I admire your presentation. Stating the goal, identifying the items purchased to meet that goal, and then presenting a verdict.
I don't have a feel for how much is too much. I felt I bought a lot of new items in one month's time. It made me a bit uncomfortable, but if this new system works for us, I think we will both find it to be advantageous in the long run. I already can see a certain efficiency that appeals to me. And knowing that I am done shopping for the season (not a fast, but light snacking) seems to relax me. I can enjoy fashion without any pressure.
You did GREAT on the bottoms. I lusted after every single one you listed. Buying interesting tops is really, really challenging. I can understand why you might feel you "settled for tops more than any other category, and still feel lacking in ones you love." I think you did well because you used the wisdom of the Forum and you really analyzed each and every purchase.
Being specific about your future wants is a great idea too. I find a nebulous or unformed idea hard to shop. I come home with garbage because I didn't really know what I wanted in the first place.
YAY for you.
