Suggest you start one lifestyle category at a time.
I also work from home. Since you say the reality is that you are apt to wear gear at home (and I do too), maybe give yourself a pass on this capsule, and just make do with gear and don't plan to invest any energy or money here too much? That way you can spend our focus in the other categories instead.
It sounds like you are covered in the fall/winter formula category -- maybe it's not your dream wardrobe, but you're not going around naked either.
I suggest therefore you start with "appearances" category, as that is a smaller category, and you have less here. It also sounds like a lot of fun to start with, if you ask me! This is where you can focus on "less is more" and add a few awesome statement pieces.
What may happen is that those statement pieces find there way into your fall/winter formula. I would not be surprised....because that's how it happened for me. Except my category wasn't "appearances." Let's call it "events"....
The hubby and I often go out to theater, art gallery receptions, concerts, dinner out with friends at trendy restaurants, and things like that. I imagined how I wanted to look at these events, after paying attention to what other people were wearing. There is a whole range of events -- I wanted something with artistic flair and edge for art events; something black and rocker for concerts; something classic for theater, etc, etc. A whole bunch of different moods and personas. So I built this category first, but found that a lot of the items I bought could be incorporated into other aspects of my life. Call this the "aim high and trickle down" effect.
Take for example, a velvet jacket. Mine is black, cropped/cheeky length, and has ruffles. Initially I could not wrap my head around wearing it for anything other than formal events, like a night out in the theater district, over dress slacks or an LBD. But then I realized wow it looks great with skinnies tucked into sleek tall boots, with a more casual purse, and that works for all kinds of events. Drag show at gay nightclub? How about pairing it with navy silk blouse, long strand of pearls, white clutch, skinnies tucked into funky tall wedge boots?
And why not even wear it to work, with black shell, chunky pearls, my COH denim trousers, crackled black leather "serious-for-business" bag, and sensible red patent leather pumps? Heck I can even wear this to laid-back Sunday brunch if I swap out the shoes for ballet flats, and wear a graphic tee or denim shirt, collar popped, underneath.....
Start ONE statement piece at a time, for the appearances category. Then live with that item and see if you cannot get it to play with the rest of your lifestyle.
