If you are absolutely sure of how strong your wave pattern is, then I'd say go for it! But for some wavy haired people, curls tend to show up with length, and when they cut their hair, it can pull out the wave. Just go with what you are comfortable with! It just depends on you!
Curly and PROUD!!!

My hair has a mix of low/med/high porosity, and it's medium textured (some are still fine, though!)
