Depends on bone structure. Some people looks better with straight while others look better with curly, ofc there’s also the different types of curls and way youstyle them. I think I look better with curly hair, generally get more compliments wearing my hair curly than when I straighten it.
Bone structure is key, os it depends. I have wavy hair though and think I look better with wavy hair, though it needs to be styled. I do envy straight hair though for the ease of maintenance at times.
