Med Heather Gray against deep blue is a blue palette with real range. Cooler up top, deeper below, and the whole thing reads intentional. The cotton-blend knit has just enough weight to hold its shape without bulk. Open office, glass walls, everyone can see everything. You're fine with that. The morning decision was fast because there wasn't one. These two pieces just work.
Finish with dark leather loafers or matte black Chelsea boots.
