<human>:  What is the difference between a tuxedo and a suit?
<bot>: The primary difference between a tuxedo and a suit is that a tuxedo is typically made from formal fabrics such as satin or silk and features details such as a pleated shirt, silk lapels, and black bow tie, whereas a suit is a more casual garment usually made of less formal fabrics like wool or linen, and features details such as a plain shirt and tie.
