<prompt> Human: I was previously working at a company with a very casual dress code. I disliked my job and felt my appearance generally went unnoticed, so unsurprisingly, I didnt put much effort into my work clothing. I start my new job in just over a week. Im very excited for the new opportunity and am motivated to make a good impression, so Ive been stocking up on a good 2-3 week rotation of business and business casual clothing. Once I get my new wardrobe established, Id like to do a better job maintaining it. Whats a reasonable amount of your take-home pay to invest back into your work appearance on a monthly or bimonthly basis?  <response>: I started a new job with business casual dress about 6 months ago. I would advise that you first make sure you know what their definition of business casual is, because its a fairly loose term. Generally its some form of a dress shoes, dress slacks, and a button up shirt with no tie, b khakis or dark wash jeans and a polo, or c not old jeans and T shirts which kind of includes a and b. In my case, my job unofficially is c, so theres a pretty wide range of dress adopted by employees. I personally dress as described by a, because I think its good practice to dress as nicely as possible without looking out of place. It would be nice to find a reason to visit the office during the workday before you start so that you can take note of what everyone is wearing, particularly in your department if you didnt do that at the interviews.As for your actual wardrobe, my advice is to make it modular such that there isnt really any maintenance until a particular item wears out. Come up with a system that allows you to mix and match such that you can create many outfits with a smaller rotation of clothes. This keeps your wardrobe looking fresh without breaking the bank, and makes it EASY. Find an affordable brand for shirts and pants that you like, and get a few of each in a variety of colorspatterns. My work wardrobe is about 10 button-up shirts, 7 neutral pairs of pants grey, black, etc., a pair of black dress shoes, and a pair of brown dress shoes. Even this is really overkill, as I could technically go 140 work days without wearing the exact same outfit maybe a bit less because I have a few patterns that would clash. You could get away with much less if you wanted to; your coworkers very likely will not notice. I would keep it minimal at first, maybe a few shirts and a couple pairs of pants, until you decide whether you like the job and will be staying there for a while.FWIW, I on many occasions have gotten comments from my coworkers and managers about how well I dress, when really Im just mixing and matching button-up shirts and dress slacks! Its very easy and makes a good impression as long as you again dont look out of place.
