The type of shirt that is worn really does depend on the style of suit that is chosen. If you are wearing a classic morning tails or Prince Edward suit with a cravat the obvious choice is a classic wing collar (similar to the type worn with a tuxedo) or the more contemporary Victorian wing (also called French wing).
The colour of the shirt will wither be white or ivory depending on the colour of the bride’s dress. Another factor that can determine the colour of the shirt might be the waistcoat and cravat you choose to accessorise the suit. If you are wearing brown, cream, beige or tan shades then an ivory shirt is a must. White shirts look crisper inside silvers, greys and numerous other hues.
The Victorian wing is increasingly becoming the choice of the wedding shirt for wearing with traditional, classical groomswear. It’s high swept back and long wide wings really accentuate the style of a self-tie cravat.
Some people still prefer to wear a necktie with tails and if that is the case I would recommend a normal Kent collar shirt in wither white or ivory. It is essential that the collar and fabric of the shirt is well finished and a 100% cotton texture is preferable.
With the recent upsurge in the popularity of the normal day suit, there are more and more people choosing a normal, white or ivory, Kent collar. It can be nice to wear a slightly cut-away collar, which will show off a well-made Windsor knot more effectively.
One other factor to consider is the fit of the shirt. Most manufacturers offer a slim fit of the model now and, if available and your body shape permits, it is the recommended choice.
