my summer uniform has pretty much been a t shirt/button down, chinos/jeans, and chucks/BB deck sneakers/CPs.
The only difference in the winter is that I'll throw on a few more layers (cardigans, hoodies, and jackets/coats) and swap out the shoes with a pair of Red Wings.
If anything, I can say I really appreciate classic american pieces (OCBDs, for example) and wearing them in until they're soft and frayed.
Also, my color pallete tends to somewhat bland and nuetral. Nothing beats a heather grey t, IMO. the only real pop of color comes from my socks and in the winter, my scarves. The only white socks I own are these thom browne-esque ones with red/blue stripes that I picked up at UNIQLO. When I wear a suit, however, I like to play aorund with my shirt, tie, and pocketsquare color.
Right now im wearing a white t, slim-fitting chinos, pink/grey horizontal-striped socks, and blue BB deck sneakers.
