It's been an emotional rollercoaster for sure, Una (I'm so sorry about your friend's husband).
When I first read you got a new job (belated congratulations), I also immediately thought of a few amazing, well-cut suits. Jules makes a great point about the uniform. These suits + tops + footwear & bag, can become your work uniform, and worn individually they might also be able to do double duty for off-work weeks and weekends.
How about pairing the suits with button-downs (you're not the biggest fan of them if I remember, but perhaps you could give them another chance?) and more Una-like tops, and go for an androgynous work look - I can see that working with your style preferences. Footwear: in warmer weather: flat oxfords and slipper flats, colder temps refined and/or tougher flat booties and ankle boots, like Chelsea boots (also love it when trousers are tucked into those, but not sure if that would be OK on the job?).

Hang in there, Una!
