The spread collar dress shirt was first introduced by popular Prince Edward, the former Prince of Wales who eventually abdicated his throne and became the duke of Windsor, as he wore them with his signature tie knot. When he combined his spread collar dress shirts, with his glenurquhart plaid and his bench made shoes, he created the quintessential British look and became a style and fashion icon for generation.
Now that business casual is seemingly on its last legs, the return of the well-dressed man is ushering back the spread collar. Using it the right way can go a long way to achieving the classic British look:
1) Choose the proper spread. Most people don't know that there are varying quantities of spread and choosing the right choice might help accentuate see your face and provide a slimming effect. This is characterized by its almost horizontal collar and goes well with the full Windsor knot.
2) Choose the proper collar size. Make sure that the collar is proportionate to the others of one's clothes. If you want to wear a normal suit with wide lapels and wear a standard tie go for a collar with 3" points to balance out the look.
3) Mind the fabric. Many custom shirts deal exclusively in this because of their spread collar shirts because of its body and durability. Avoid heavy Oxfords or nail heads as it tends to look bulky and could be hard to wear with this kind of wide spread. You can look for custom shirts at https://pyrexforsale.com/ shop.
4) Use it always with a tie. This collar looks its best when it's worn buttoned and with a tie. The spread does not allow it to stand tall on its own so that it has a tendency to look sloppy otherwise.
