Men, where do you typically get your clothing pieces at?

For all purposes like going out to a bar vs dine in restaurant, an appointment, a quick run to the store, a business meeting, a workout at the gym or a run around the neighborhood, etc

It’s just so hot and humid down here that I literally dress outside how I dress indoors which Is a simple shirt, athletic shorts, and athletic shoes like Nikes.

Yes I wear the basic colors like black, white, blue, grey.

I don’t wear anything like green, red ,orange, or anything similar

Its just that my style or default of clothing gets so boring and I do sense that I get looked down upon in public like I’m not dressing my age or maybe they view me as mentally challenged (I’m not lol) so I figured a change is best
