^ what a clear-sighted list. I'm working on getting to that point myself.
I notice you have a lot of black items on that list. Black is so versatile, so I find myself filling in holes in my wardrobe with black. I recently got a black mini-skirt because I hope it to fulfill a broad category of need: the going-out basic. I just received in the mail today (eBay auction) and I love it! Just the perfect fit.
I lucked out since I got it on eBay, but it helps to know what brands work well with my style and figure, especially in this whole minimal wardrobe endeavor. It helps me to focus my search. For me, Twinkle by Wenlan works out well because she has the cute, quirky, well-made aesthetic I go for.
