More tips for men:
Shirts: Pick shirts either in a solid color or that have a formal-looking pattern like plaid or oxford. You can wear polo shirts, but make sure there are no big logos on them. Always tuck in your shirt.
Pants: Pants should extend to the top of your shoes or be slightly longer. If your pants are too long where it bunches up at the bottom or you are required to fold them, this is considered to be too baggy and unprofessional.
You can wear a blazer or a V-neck.
ALWAYS accessorize with a neutral-colored belt.
