Hi Veruza,
I have been studying this dance form almost entirely from video for about seven years.
The videos that I wish
that I had started with are "Bellydance Movement Foundation" by Yasmina Ramzy (not Serena) and ""Volume 1 - Arms and Torso" by Sahra Saeeda. Both are available from Dahlal International. Dahlal does not compensate me for the referral.
And for an "eye on the prize-big girl dancer" video, "Serious Bellydance" by Tamalyn Dalal.
I found that "Core Fitness" filled in nicely with "Bellydance Movement Foundation" and "Volume 1 - Arms and Torso". As Ayshe says, "don't be a wiggle bunny!"
Hope that this helps. May your journey be bountiful!
Ruby,
