In person attire question

Hi guys, I will be attending my first AWS conference at a booth as a mid market AE (big time imposter syndrome). I was curious what my attire should be. I also have an in person sales event in August where I will meet the team, we are remote.

I need to buy some dress shirts for sure, was curious if anyone knew a “type” as the ones I have can be pretty formal with big collars and look back untucked.

Also should I buy/wear a sports jacket? Any recommendations on style/color?

Finally, are nice suede Oxford shoes ok? Running shoes?

Thanks and sorry for the dumb questions. Not sure where else to ask and nervous.
