What advice are you looking for? Fashion? Where to buy? Fit? How to wear a suit when coworkers don’t? My advice for fashion and fit is to find a picture of something you like and go to a reputable men’s suit retailer. They will help you ensure a proper fit and offer custom tailoring (which might not be optional). Get the suit tailored and give feedback as to how you like your clothes to fit. Take the shoes you want to wear with the suit. Allow the tailor to measure you and help you with the fit for your body type. When you pick up the suit after tailoring, try it on again to ensure it is how you expected it. If not, have them make adjustments. A suit that is uncomfortable stays in the closet. Pick out two different color shirts and two different color ties. Again, the professional at the store you picked can help with color, fit, and selection. This will make your suit more flexible. Be prepared to spend some extra money on appropriate accessories as well (like a belt and socks). Ask for a garment bag with your purchase to ensure you keep your new purchase in good shape while hanging in your closet. Dry cleaning is a must with a nice suit, but if your don’t expose it to harsh treatment (rain, wind, dirt, etc) you should be good with several wears before cleaning is necessary.
