Ahh, self-imposed maintenance chores. You're gonna rue this one
I'm not sure whether "fashion" is its own category like business, casual, or business-casual? Before construction begins, you need to define the goal criteria. I missed this in case "fashion" really was a goal in which case I don't even know where to begin.
In Chicago as a stay-at-home cult leader, I really only have two goals which reflect the climate temperature: hot as hell and cold as fuck. The high-quality solutions here are
1 pair of [tactical] shorts (from 5.11 in my case) for the former situation (call it summer aka hot as hell)
1 set of [worker] insulated coverall (from refrigiwear) for the latter situation (call it winter aka cold as fuck)
I could have a third capsule for when I have to look civilized. This would be something like what I wore in the youtube interview; alternatively, I could pick and stick with a dark grey suit + turtleneck which is what I use for interviews.
What's my point? This would theoretically work for ALL my needs. I do have more clothes than this but this more than anything reflects having relocated from one climate to another faster than I've been able to wear previous clothes out. As a result, I now own clothes (pants, t-shirts, ...) that I can only wear effectively for a few weeks a year, mainly spring and fall. Of course this would change if I was morally willing to gun the HVAC harder thus establishing a more uniform indoor climate that was more out of whack with what nature offers at my location but I'm not. Therefore, we need to know what climate and function you're aiming at first. I've run into minimalists who wore a classical suit at all times ... talking them into going hiking was quite a challenge. Oh yes, the point... the point is that I could ditch the rest of my wardrobe. (It's not big .. about the size of the one you proposed anyway.)
Insofar fashion just means "looks good", the problem with quality is that it's best if quality matches throughout. This also holds for areas outside of clothes. If you upgrade one part of a whole, then suddenly the rest begins look shabby in comparison. This begets upgrading something else ... and now you have a fashion-inspired hedonic treadmill. One thing that happened to me when I tried this was that I ended up with a bifurcated wardrobe. One part had ratty clothes and the other part had fancy clothes and the two could never cross making for a huge lack of minimalist inefficiency. So if you do go that way, you will eventually have to choose a side. I chose not to play.
