Beautiful girl with a great personality and smile. They can usually be seen to have a resting b*tch face but they really aren’t one. They are very protective of their friends and family, but once you do them wrong they’ll either scold u with her rath or just hold a grudge for a really long time. Most Matiana’s are dark hair, dark eyed because they are usually Mexican or Hispanic. They are also hard working and intelligent girls. Though they do search for love a lot so sometimes they have really bad taste. They can also be a little dramatic but only for people they really care about. Overall Matiana’s are just really amazing girls that you should keep around
Wow Matiana is such a gorgeous girl
