Adelfa, congratulations on meeting the pattern goal!! I have a small goal of buying a few carefully chosen pattened items this season, too, because I know that pattern adds such interest to a wardrobe, even if I have to fight myself to buy it.
"Small and efficient but not minimal" -- to me, this means something like Sveta's closet, Angie's closet, or (I hope) mine. (Maybe lots of other fabbers, too -- I just don't know the contents of their closets as well.)
The ten item closet would never ever, work for me. It appeals to a part of me on a visceral level -- I dislike waste, I like structure and calm, I would love 10 carefully chosen very high quality items, I don't mind repeated items or outfits, I love a wardrobe that remixes easily, I'm love editing and purging -- I enjoy the process of streamlining. So all those factors make a very small wardrobe extremely attractive to me.
But in the end, I've found that I can't do it. I can't do it psychologically, because while I love to repeat items and whole outfits within a season, I also love to have pretty new things -- at least a few -- every season. Also, I get extremely bored of the same silhouette worn constantly, and need to switch that up from time to time.
I can't do it practically, because my weather is so extreme, that as Joy said, it's just ridiculous to expect the clothes of one season to be wearable in its opposite. Meanwhile, I have lots of different kinds of activities, regularly, and they require different kinds of clothes. I have work-at-home wear (which is typically super casual). I have smart casual for outings in my small, mostly casual university city, and and business casual for my frequent trips to the bigger city. I do a LOT of travelling and often to different climates. I need an "appearances" capsule, which sort of crosses categories a bit, but includes some dressier clothes as well and requires a bit of trendiness (and thus, frequent updating). I need clothes to wear to the theatre and out to dinner with my husband or friends. There's gear, of course, because fitness is a big part of my life and I spend time outdoors with my daughter. And sleepwear and loungewear.
On the other hand, I equally couldn't live with a very large closet. I'd be overwhelmed. I love seeing the variety of clothes and outfits on some of our Fabbers who have large closets. But for myself, personally -- I'd be wracked with guilt that I wasn't wearing certain items enough (heck...that already happens, and when it does, I purge like mad to get rid of the evidence!!) and if there came a time when I didn't know the contents of my closet or forgot I owned this or that...well, I'd just feel really uncomfortable.
Note -- that's not a judgement. I'm not saying that big wardrobes are "wrong." I don't feel that way at all. I just know a really big wardrobe is wrong for me. Too much Calvinism in my own closet!
But equally, too much frivolity and attachment for the truly zen closet, I guess.
Realistically, I probably do something more like a 40-50 item closet per season. Depending what you're calling an "item" (e.g. does footwear count? do coats? Does gear?) Anyway, I am talking just about clothing. And I make my own seasons in 6 to 8 week blocks, which roughly correspond to our seasons here. And rotate items in and out of my main closet on a seasonal basis.
Note that there is overlap between seasons, and a few items are truly all-year. I have a black dress that's all year, my jeans, a few shirts. So I'm not saying that I own a total of 400 items!! In fact, there is plenty of crossover except for the coldest and hottest seasons, which almost have their own mini- capsules. But you get the idea. I do regular "weeding." So...as the temperatures heat up, the navy jacket that I worse in spring moves to the second closet, while the Zara kimono comes to take its place.
Keeping my clothing moving and only leaving what's seasonal in my closet is another way I simplify. I find it mentally jarring to see heavy wools hanging next to cool linens, so I need to do this.
But I realize that for some people, all this switching of clothes around might feel complicating!
