The windowpane suit is a bit more stylish than the pinstripe and solid color suits. This suit is pattern is created by running lines both horizontally and vertically to make square "windowpane" patterns.
Parties, religious events, and less formal social events are great places to show off this type of suit model. However, this suit is usually not formal enough to wear to the office, and certainly not professional enough to wear to an interview.
Matching this suit with a nice tie can require some skill on the wearer. You must remember to take into account the size of the windowpane pattern versus the size of the tie pattern as well as the colors. However, matching this suit with a stylish shirt and tie can be very rewarding in the end.
