Most of our shirts have collar sizes from size 38 to size 45. Due to our unique size system, each size has its own fit. If you are looking for a shirt that fits slightly wider, simply choose a larger size. The collar will be 1 cm wider, and the shirt will be a whole size larger.To start with, we make our shirts with unconstructed collars and cuffs. A non-fused or unconstructed collar is more comfortable to wear and gives a nice collar roll. The front and back of the collar are not glued and are not reinforced by a nonwoven lining. This way of making a soft edge requires years of craftsmanship and experience. Because the collar is not stiff, this shirt has a luxurious and sporty look.The Shirtbird slim fit shirt is fitted due to the two darts on the back of the shirt. By using darts to tailor the shirt, the shirt gets a more natural curve and a sartorial appearance.When possible, we like to finish our shirts with Mother of Pearl buttons, this emphasizes the luxurious and sartorial character of your shirt. We attach the buttons on a Ascolite way, this makes it easier to button and unbutton the shirt. And the best of all, the buttons never fall off.If we want to give a shirt a more casual look, we wash the shirt after the shirt is completely manufactured. Pre-washing gives the collar, cuffs, and seams a fuller and more informal look. Just think how pre-washing makes your jeans more beautiful. After washing, the shirt is ironed, and laundry packed.
