Make sure you have these three collar types in your business wardrobe. And know how to pair them. Not all suits and ties go with all collars.
The Button-Down Collar
Very American. This is the least dressy collar choice; as such, you may want to look for a shirt cut from broadcloth (like the one shown here) rather than oxford cloth. You don't want a shirt that looks too casual for your business suit. This type of collar works best with medium-width ties.
The Straight-Point Collar
Always a safe choice. The collar's narrow stance means it tucks nicely into high-cut three-button suits. Good for narrow-to-skinny ties.
The Spread Collar
The most dashing, confident collar out there. Best with a medium-to-wide tie. And go for a traditional four-in-hand knot; it's okay for a bit of the tie to show around the collar. And with a smaller spread collar, you'll want to keep your tie knot on the tighter side.
Choosing a Shirt Cuff
1. Single-Button Standard (left)
The most common type of cuff, which you'll find on most moderately priced dress shirts. When fitting properly, it should reach the hinge of your wrist.
2. French (center)
The dressiest, most formal cuff choice. But you don't have to wear flashy cuff links and (after work) a tie with them. Try an open collar and more creative links.
3. Two-Button Barrel (right)
For the guy who wants a shirt with as much flair as his British- or Italian-made suit.
