M.F.
I don't know about Carrollton/Farmers Branch area, but just for reference, the studio where my 3 yr old attends is $50/month for a class that meets once a week. There is a small discount for paying a semester at a time. We like this place because they weren't as strict on dance attire for the 3 and 4 yr old girls. They understand that dance gear is expensive, and it's just not practical to spend so much for a 3 yr old who may end up not liking it or who might grow 2 shoe sizes in a school year. The instructors really try to make dance a positive experience for these little ones and their parents.
Also, they go to great lengths to make sure their performance costumes are age-appropriate and modest.
No plunging necklines, etc.
One of the main reasons I like this studio is that the instructors really emphasize worship through movement. It's a Christian-run studio and their faith is evident in the way they do business.
