I suggest merging this question:
I have accepted a new job at a particular company. The company has casual attire (Jeans, T-Shirt). I have even seen some people wearing shorts (I would pass on that!).
Since, I will be joining as a new employee how I should be dressed for 2-3 months. Should I still wear formal attire (full sleeves with dress pants).
Also, how can I make a good impression as a new employee? I will be in a senior level position and I will be responsible for training other employees on certain technology.
Into the older:
I have accepte d a job offer as a software developer after two phone interviews, and they told me that they have a relaxed dress code. Specifically, they mentioned wearing jeans. However, I'm not sure whether that's jeans with a polo, or a button-down shirt, or a T-shirt; and I want to communicate on my first day that I take the job seriously. Is it acceptable for me to show up on my first day in (nice) jeans (particularly if I wear a nice shirt)? Is it a bigger risk for them to wonder why I'm in jeans on my first day, or for them to feel like I'm overdressed?
These questions seem to ask basically the same thing and have 6 answers each. Both refer to a workplace with full casual dress (jeans). I'm not entirely clear on the protocol for what the merged question's text should be but both can benefit from some rewording, presumably the post should be partially rewritten but that can be discussed if the merge has support.
If no consensus is reached in favour of a merge, at the very least the newest question should be closed as a duplicate and all future questions like this one redirected to the oldest question:
