If it's just for shaping, especially stovepipe, Latin is really a good choice. Latin becomes slim by twisting and stretching the fat film. After studying rumba and cha-cha for half a month, although I haven't lost much weight, my legs have become thinner. Moreover, Latin dance can especially cultivate temperament.
But all dances consume calories, and with the deepening of the learning process, it is necessary to stretch ligaments and stovepipes. Personally, I suggest you learn jazz. First, your body has been shaped, and Latin softness will be poor. Secondly, learning dance now is mainly to add a skill for performance. Jazz is more performative and easier to learn.
If time permits, you can get in touch with Latin in your spare time to improve your health.
Ps: I'm two years younger than you, and I didn't start dancing until I graduated from high school.
