As an Indian immigrant to Minnesota in the 1970s, my dad adopted a habit of ALWAYS wearing a suit. This gave him the benefit of the doubt in a lot of interactions where he wouldn't have otherwise had it. He kept up that habit for a long time and wore a suit to parent teacher conferences, my 4th grade violin "concert," etc. It most certainly got him a deference from others and did its job admirably.
He never got OK with my habit of wearing jeans and T-shirts even as an adult because he couldn't grasp how different my experience was from his.
