That's true although professional dress is definitely more casual in the US (for the most part) than it was 20-30 years ago. When I started with a tech company in the mid-80s, suits were pretty much the norm for marketing and sales and even many in engineering. It would have been strange for the most part to, say, give a presentation at a conference without being dressed that way.

These days, in tech certainly but across many industries, "dressing up" is mostly an outlier.

I can remember my dad in the late 80s early 90s wearing a suit as an EE. Slowly it changed from suit to shirt and tie to no tie. Now it’s polo and jeans.

Many companies are trying to emulate west coast tech companies. Especially Silicon Valley. I’ve seen a lot of initiatives geared toward “millennials” in a couple big companies I worked at. Including getting rid of the khaki business casual.
