standing out in a big group

By correcting the spelling of the bosses!

Have you played a competitive sport? Football, basketball, baseball? Its like the beginning pre-season practices, no one knows you or your abilities. In your situation, your like a freshman on the freshman team. All you can do is be a high performer, work hard, do what your told, be consistent, and be a leader to your peers. This is not over-night but the repututation is created over months if not years.

Its all about blocking and tackling. The best players know this. That should be your goal and everything else will settle itself.

One thing I got told over and over was "safe pair of hands".

Good looks, lol.

Be the one everyone can rely on. Don't complain and do as you're told. This is an achievement in Banking.

repeatedly ask your MD questions like this one

A pink shirt

never do anything visibly different (suits costing 10x other analysts, liberty spikes, being the drunk one at office parties), as others have said be consistent in your work, don't complain, and be the one people come to for work and be genuinely helpful to others (note: not annoyingly helpful)

^^^Are expensive suits really that bad? I agree with your other points but why does it matter if you like to dress well?

The Chinese has a special word : "DiDiao", which means to have a low profile. Not sure if it suits here.
