Dressing Proper. Is it still a thing?

In the modern world, a trend has emerged wherein professional attire has ceased to hold a place of utmost importance. And, courtesy some contemporary work sectors and their relaxed way of working and communicating, turning out in professional attire is losing essence very fast. Although it would perhaps be unfair to emphasize about your exterior self instead of your skills and abilities but one’s attire has an important role to play to make a required impression. And not just that, being dressed according to time, place and work also gives a confidence boost knowing that you look good and are dressed appropriately. Please share your thoughts on dressing up in a decent manner and keeping your surroundings in mind.
