So there is an exception to this rule of mine. Some companies have a "dress code" which in certain sale scenes I understand and in others not so much. If that is the case, there is nothing you can do sadly. I'll give a reference. In my field specifically, when going onto a jobsite very rarely do they want to see someone in khakis/polo/white hard hat. 1. You come across like a supervisor 2. If you're not coming across as a supervisor - You're coming off as a salesperson 3. Audit companies typically have the same attire I've had the best responses from people wearing jeans, boots and a company polo/company hoodie. It makes you seem more relatable to the client. You're not coming across as "better than them". This isn't always the case but you want to blend in with the environment you're around. It makes people more comfortable from a psychological standpoint. In my experience, clients do not seem as standoffish at first. This specific study of mine, might be more field specific to myself but I'll give examples below: Medical Sales - If your company allows it, wear scrubs or business casual Real Estate - This one is tricky, but I would say tailor yourself to the degree of the house you're selling. If you're selling $100-200K houses, dress well but don't show up in a suit. $300-500K houses, may want to up your game a little bit but I don't think quite suit field just yes. $500K-1m+, this is where I think going in with a suit is more appropriate. Feel free to comment your thoughts on this. Finance - Generally your clients are all going to be suited up or minimal business casual Technology Sales - This is a broad spectrum environment. I've seen ranging from t-shirt and jeans to business casual These are just a few industries off the top of my head. Overall key takeaway from this - Make it feel like you should be there. As you should, this is your job to help these clients.
