The pocket chief is the element that gives an elegant and exclusive touch to every elegant business man. Wearing a pocket square will take your look one step further.
The pocket chief doesn't have to draw all the attention to itself but it has to compliment your entire outfit. It must be easy to wear and match: define the occasion you're wearing it for, then consequently pick a fabric and a colour.
Usually a solid colour pocket square recalls the tie's detail or, if you're wearing a solid colour tie, don't exhitate and go for a patterned pocket square you like.
