just some diff collars on shirts n how to match ties with it..
1.
The Traditional Collar is the collar that you will find on most "standard" or store bought shirts. Although you can wear a neck tie with a Windsor or Half Windsor Knot, this collar has a smaller spread and is ideal for a Four In Hand Knot. A Traditional Collar with a neck tie using a Four In Hand Knot is a basic style that is very common with American executives. If you are not wearing a neck tie, there will be a slight spread with the collar but it should still be comfortable to wear.
2.
The Tab Collar is business collar and can only be worn with a neck tie. When determining the size of the tab to be used, we factor in the size of the Neck itself. We will normally cut smaller Necks with a 3/4" tab and larger Necks with a 1" tab. That gives the customer enough flexibility to choose the Tie Knot that is most appropriate. If you want to "squeeze" the tab sides together a Four In Hand Knot is probably most appropriate.
3.
The Button Down Collar is as traditional as it gets. The Button Down Collar can be worn with a Neck Tie or it can be worn without in a more casual style. Because of the way the collar adjusts, you can wear any Tie Knot that you want but this would be another collar where a Four In Hand Knot is probably most appropriate. In a twist to the traditional Button Down Collar, we also offer an Inside Button Down Collar where the buttons are on the inside of the collar (invisible) and attach to a tab on the inside. What you end up with is similar to a Tab Collar where the collar halves are held down. You can see this Collar below.
4.
The Pin Collar - Straight Collar is another business collar where the neck tie gets squeezed between the collar halves. Instead of using a tab to achieve that, a pair of holes are are cut into the collar so that a Tie Pin can be thread between the halves and keep the spread small. The Tie Pin has to be purchased by you, we do not sell or provide them. This collar is not appropriate for wear without a neck tie. The type of knot that you use is up to you and the size of your Tie Pin, but a Four In Hand Knot is probably best.
5.
The Quarter Spread Collar is one of the larger spread collars that we offer, this is sometimes considered a more "European" collar. The Quarter Spread Collar is halfway between the Traditional Collar (little spread) and the Half Spread. On a Quarter Spread Collar it is more appropriate to use a Windsor Knot or a Half Windsor Knot. The fullness of these knots is going to help cover some of the spread at the Neck. These collars can be worn without a neck tie but you might find that the collar points will hang up on your collar bones and make the back of the Neck of your collar not rest flush with your Neck, but instead will bow out away from the back of your Neck.
6.
The Half Spread Collar has the largest spread that we offer, this is sometimes considered a more "European" collar. The Half Spread is cut so the spread looks somewhat vertical on your shirt. On a Half Spread Collar it is more appropriate to use a Windsor Knot or a Half Windsor Knot. The fullness of these knots is going to help cover some of the spread at the Neck. These collars can be worn without a neck tie but you might find that the collar points will hang up on your collar bones and make the back of the Neck of your collar not rest flush with your Neck, but instead will bow out away from the back of your Neck.
7.
The Inside Button Down Collar is the same as the standard Button Down Collar except the buttons are placed inside the collar. A tab is also added to the inside of the collar so that they can attach to the buttons. This way you can have the collar stay in the same position as the Traditional Collar but have the collar points stay close to the shoulder blades at all times. This collar is another option if you like the Tab Collar but do not like to "squeeze" the two halves of the collar together.
8.
The Small Spread Collar is another unique collar, it has very little spread with the collar halves coming almost straight down. The edges of the collar are rounded for a softer look. Their is a small space at the top of the collar for wearing a neck tie. This shirt should be worn with a neck tie. This collar is sometimes called a "Soprano Collar" or "Mafia Collar" or even a "Continental Collar" because it is worn on the European Continent.
