Generally, shirts are sized by their collar. To find the correct collar size, measure around the neck with a tape measure, taking care not to pull the tape too tightly. For comfort, and to allow for collar shrinkage in the wash, the collar size chosen should be half an inch greater than the neck size measured.
Off the peg shirts are available in an array of fits – if you have a chest size of under 38 inches, it's best to go for a slim fit as this will flatter your appearance. Obviously, the best-fitting shirts will have to be made to order – the fit of off-the-peg shirts is always going to be a compromise.

Fabric
Pure natural fabrics will give the best results, and cotton is generally accepted as being the classic shirt fabric, being light, airy and cool in hot weather. Cotton shirt fabric comes in a vast variety of qualities – aim for good two-fold cotton with a yarn count of at least 100 for a soft fabric with a great sheen. Singles cotton is available at a lower cost but is more prone to pilling. Linen shirts are also a good alternative for the summer season as they remain extremely cool on hot summer afternoons.
Color
White remains the classic shirt color for formal occasions. Originally worn to indicate that the wearer could afford to wash his shirt before every wearing, this tradition has carried on today and is the default choice for all formal shirts. The cream can also be worn on these occasions.
