Dress Shirts are also called a Tuxedo Shirt or Formal Shirt as well as a Dinner Shirt
Going to a formal occasion? Better to buy a new shirt and get your correct fit, rather than hire a used shirt. Van Heusen have a Classic Fit or a European Fit. Ganton Shirts are a premium quality dress shirt hence the higher price.
Most dress shirts have a pleated bib front or a honeycomb effect bib front called a Marcella Front, the choice is purley to your own taste. The collar is a choice between a wing collar or a peak collar which today is a peak collar more spread out than the past, so now called a spread collar. I would say 95% of formal dress shirts are white, however a fomal wear specialist may stock some coloured ones.
