When in a long-term relationship, date nights can be a fun way to mix things up from the daily routine. To help add to the excitement around them, dress up on the more formal side to make things extra special. By dressing up, you can get further from the daily return and really enjoy the date.
Any business casual outfit is appropriate for a date night. The proper attire for the date will depend on the location of the date, but at a minimum the basic business casual clothing items should be worn. This includes a dress shirt, dress pants and matching shoes. To really spruce up the evening or if the date is held at a more formal location such as a nice restaurant, add in a matching sport coat
Don't wear what you normally wear. Change it up to keep the night special
