When it comes to fabrics for semi formal men’s suits, wool and cashmere are the primary choices as these rich fabrics portray the refined style much better. It is not appropriate to wear a seersucker or linen suit to semi-formal events as they don’t match up to the level of formality.

A tailored corduroy jacket in quiet colors like blue and brown with matching pants is certainly acceptable as semi-formal for the fall and winter season.

The tuxedo is considered the ultimate white tie formal outfit. On the other hand, a three-piece suit is an outfit fit for semi-formal wear. Let’s understand the difference between a tuxedo and a suit.

  1. Satin: One of the ways to tell a tuxedo apart from a suit is its satin details. The glossy fabric is often added to the lapels. Often a side stripe of satin runs down the length of the pants as well.
  2. Buttons: The buttons on the tuxedo are made of satin, whereas those on the suit jacket are made of plastic or covered with other fabrics.
  3. Extra elements: A tuxedo is accessorized with some extra elements like the cummerbund, bowtie, suspenders, and waistcoat which makes it more formal. Though every tuxedo design may not include all of these accessories, it is a differentiating factor. As for the suit, it can be worn with or without the tie or the waistcoat depending upon the level of formality required.
