Belly Dance is the one dance form that actually encourages and welcomes bigger women though. I have seen all ages and all sizes do belly dance
But I will say this, I choose to do Tribal because I didnt like the caberat costumes ( The ones most ppl think of when they think of belly dance, slit skirt, sequins, whole belly bared, ect ect..)
Tribal belly dance is a bit different and would probabbly be a good place to start, the moves are sexy but in a earthy, powerful way..and some of the moves are just more africian/india folkloric dance moves that more tell a story of harvest, of fertility, of birth and death, its not a dance of *seduction*
(although you can take some of the moves and take them home and if you wanna dance a dance of seduction with 7 veils..**** I aint gonna stop my students you know?

)
what they do at home is their own business
but in class..lol the moves are meant to tell a story of life for women in ancient times and modern times and we dont dress all sexy to class..we come in with thrift store broomstick skirts and tshirts..hair up in pony tails, no make up, and like I said..my students are of all ages and sizes, the particular class I have right now, there is only one thin student, the other 7 are actually my size or bigger..
and the age ranges are from like early 30's to late 50's..
and from what I know most belly dance classes are like that..alot of belly dance teachers I know are not skinny young things by any means..
its a pretty laid back usually..
now my daughter takes ballet..
dear god..lmao I couldnt survive that..her teacher is so dam picky and strict and her students are all lil bitty over achievers..lmao
I would love to learn ballet..but there is no way in **** I am walking into a class like that for adults..
I am wayyy to much of a rebel
but belly dance..shoooot..were totally laid back
