Got invited to a hiring event for a security guard position and they said Professional attire is required however this is only my 2nd job so I have no clue what to wear and don’t even think I own anything that is professional so I’m here seeking help what do I wear? (Also I’m kind of on the bigger side)

Edit: I messaged them asking this By professionally you mean a whole suit or like business casual? And they replied by saying business professional
