Kylie frequently wears a black cloak while traveling so that it's nearly impossible to see what she's wearing, carrying, or even what race she is though her bright blue eyes and ready smile are almost always visible.  Those traveling with her eventually see her without her cloak on.  It is then easy to see she is an elf with long, silver-white hair wearing extremely nice studded leather armor and carrying a rapier, a longbow, and several daggers along with an assortment of miscellaneous items in her full pack.
