"So, what are you wearing?"

As Wall Street internship season quickly approaches, that's a question many soon-to-be summer analysts are asking each other. 

Luckily for you, Insider's Emmalyse Brownstein has you covered on what you should and, more importantly, shouldn't wear for your first few days on the job.

One big trend Emmalyse notes in her story is the casualification, so to speak, of Wall Street. Ties and heels are basically relics of the past, and blazers seem to be not far behind.

The switch to a more business casual look can be attributed to two things. First, years of Zooming into meetings in sweatpants led to a real cultural shift in the way people think about dress codes. Suddenly, wearing a suit every day to the office didn't seem like such a great idea. 

But the Wall Street dress code was starting to change before 2020, thanks in large part to the tech community. If the new-age billionaires could conduct business in a T-shirt, it seemed reasonable to at least ditch the cufflinks. And away we went.

It'll be interesting to see how far this trend goes. Gen Zers, for better or for worse, aren't bashful when it comes to letting their voices be heard in the workplace. And they're also not ones to back down from a good fight. So as boomers age out of the workplace, could we see an even more dressed-down banker?

You might scoff at the idea, but a revolution doesn't happen overnight. It starts with some Lululemons and a pair of Allbirds, and the next thing you know you've got bankers in board shorts.
