Dressing like a so called thug? What makes one look like a thug? That comment right there is why people of color do not feel comfortable open carrying. Not everyone who dresses like a so call thug is one. i.e my wife doctor dresses like that but deliver four out five of my children.
The clothes don't make the man, the man makes the clothes
true, but first impressions last, and if your first impression to another person is nearly identical to the guys on the 6 o'clock news nightly mugshot, expect to draw attention. 'thug wear': pants hanging underneath your butt, no proper holster, with no proper upper torso wear either too little (just a wife beater) or too much (full sleeve hoodie in 80+ weather with the hood up). in that regard you are going out of your way to present yourself in such a way to draw suspicion to your activities.
both are casual as all get out. but one is gonna get you a lot more negative scrutiny.
