Girls, what clothes look attractive on a guy for casual?

I feel like I dress like a slob sometimes. When I go out to run errands I usually wear just a plain t-shirt with nothing on it with a pair of blue jeans. Along with Vans shoes. I have a ton of polo shirts that I wear if I go out with friends. I’m blind when it comes to matching colors. Any advice is great.
