Of course, when you get the job, the suits will come in handy for daily employment. Dress each day as if you were expecting to run into and chat with the president of the company. The attendees at this networking meeting were mostly in suits with handkerchiefs in the breast pocket, cufflinks, and tie bars. Most clients were slim and poised. But it is all a process of learning what is appropriate and what is not appropriate and of slowly upgrading or changing one's wardrobe in preparation for the employment process.
First impressions are lasting impressions.
Many companies have implemented relaxed dress codes on Fridays or for other special occasions, which includes a sports coat, knit shirts and casual slacks. I recommend that clients keep a spare tie and coat in the office or the car for just such an occasion. Remember-it's the impression that counts. Don't chew gum, smoke, drink alcoholic beverages, or eat or drink right before an interview. You might spill coffee on your suit while you are in the lobby waiting for the interview to begin.
