Article: Wearing a different shirt changes the whole look of the suit, which is what you want. It’s also important to wear a different shirt because it soaks up your sweat during the day and will start to smell if you wear it for too long. If you have to wear the same shirt more than once, don’t wear it on back-to-back days to give your look variety and let the shirt air out. If you need to wear the same shirt more than once, an undershirt soaks up your sweat and keeps the top shirt dryer. Even if you don't typically wear an undershirt, wear one during the week you're wearing the same suit. Besides changing your shirt, wearing different colors varies the appearance of the suit. Cycle through white, blue, gray, or other colors that look good with your suit. If you have two shirts of similar color, wear them a few days apart in the week.  If your workplace has a strict dress code, you may not have a lot of options. Vary the color as much as you are allowed. White, eggshell, and cream are different enough to be noticeable. Make sure you pick colors that match the color of your suit. If you are allowed to wear plaid, checkered, or striped shirts, this is another great way to add variety. Wear a pattern twice in the week, separated by plain colors. Switching between plain and patterned keeps you looking stylish every day. Vary the color and size of the stripes or plaid pattern, but make sure it looks good with your suit’s color. If you work in a somewhat casual setting, wear a stylish t-shirt with your suit. Vintage tees are a great item to add to a suit to bring out your individuality and personal style. Try out a plain t-shirt or a knit polo with a quarter button at the top. In cooler weather, swap in a nice crew neck sweatshirt or a thermal shirt. Whatever you do, make sure you look appropriate for your job setting.

Avoid wearing the same shirt for more than one day. Wear an undershirt to keep your top shirt dry. Wear a different color shirt every day. Pick a textured or patterned shirt for some days. Switch to a t-shirt or other casual shirt.
