Neither do the collars on polo shirts, or the patterns (or dye, for that matter) on the t-shirt you're probably wearing. If all we wanted was practicality, everyone would be wearing un-dyed ponchos - but we're not.

Some people like ties - they see creativity and individuality in the patterns, the material, the composition, the knot, and the ensemble. Just like other people see the same things in the patterns and designs on their t-shirts.

All of fashion serves no practical purpose - no need to single out people who wear one particular implementation of this.
