Check for bad breath:
Well if you brush in the morning and then eat breakfast and go to work, make sure you wake up an extra 5 mins early and brush again after you eat, so when you’re in the elevator or a smaller room, you won’t be the center of smell
You shouldn’t be caught dead with wrinkled garments, you might think people won’t notice, but in the professional business world, everything is noticed. So either iron your clothes, or carry around a “wrinkle release spray”. If you don’t have either of those, you can always hang your shirt near a hot shower for about 20 mins and the wrinkles should release themselves.
Excess Shirt Sleeves:
If the sleeve of the shirt is too big, either don’t wear it or roll up the sleeves, you don’t want to look like you’re wearing your parent’s clothes right?
Check for Stains:
DO NOT go into any important meetings or even dates with a stain on your shirt, it will get noticed and it will distract who ever it is to stare at the stain and think about how it got there.
