This is a small, French collar with short wings and a 3.5 cm. collar stand. This elegant and refined style holds its shape very well and looks great, as well as being tall enough so that the tie knot always remains above the base of the collar, while the 6.5 cm wings give it a highly contemporary look without going overboard like some very small collars.
It's extremely well adapted for ultra-formal shirts and to be combined with ties that are 6-7 cm wide.
It's also suitable for casual shirts in denim or Oxford weave if you choose a less rigid, flexible or ultra-flexible option.
