A fitted t-shirt only works for polished casual dressing if the color choice supports that effort. Neutral tones keep a fitted cut looking intentional rather than trying too hard. Black, white, grey, cream, and taupe fitted t-shirts pair with anything and read as a foundation piece rather than a statement. The fit becomes the point instead of the color. These work layered under everything and they work solo with tailored bottoms. Neutral fitted t-shirts are the pieces you buy multiple colors of because they do actual work in your wardrobe. These are the fitted t-shirts that earn their place through quiet effectiveness rather than visual drama.
