CAP (Army cap)
Army style cap is a soft cap with a stiff, , rounded, short brim of between 2 and 3 inches and a crown that is also short and around the same size with a flat top. Though this cap is a kind of baseball cap, the minimalist design of short brim and short crown match WAVE type.
WAVE type look stylish with a beanie made of middle gauge thread. And also having thin shallow rib design one is better. A beanie of flat surface made of high gauge thread is too simple for WAVE type, and a beanie of thick deep rib made of low gauge thread is too much for them. Of course a beanie made of soft material is recommended for them.
