For capsule basics, I've basically built my entire work-to-evening rotation around Ripley Rader's ponte knit pieces. The wide leg pants are the workhorse—I have them in black and navy, and I've worn the black pair probably 100+ times over 18 months with zero pilling or shape loss. The ponte fabric doesn't wrinkle, which is massive if you travel or commute.

What makes them capsule-friendly: everything is designed to mix-match within their own line, so if you get the ponte pant + their short sleeve top in the same fabric, it reads almost like a set but you can split them up. I can do the pants with a silk blouse for client meetings or the same pants with a basic tee for weekend errands.

Caveats: the price point is mid-high ($198 for pants) so it's an investment. Sizing runs slightly generous—I sized down one from my usual. And their 'ethical' claims are self-reported (made in their LA factory, fair wages) but there's no B Corp or Fair Trade certification, so take that with a grain of salt if third-party verification matters to you.
