well for the scarves i can give you some suggestions :)
the headpiece - I adore them too, you probably have to order them with the bra/belt set to really fit the colours and style (I own no bra/belt set, they re called bedlah, coz they are REALLY expensive :) ) or if one is talented I think it should be possible to make them out of glass beads and maybe coins.. but I sure couldnt

;)

for the ansuya look you might like these scarves:
www.sharifwear.com/
or something like this beneath:
www.sharifwear.com/

she often layers two scarves, one crocheted with fringe, and one with coins or beads that is shorter.

if you go to www.dahlal.com you ll find PLENTY in the "scarves" section. Go to Egyptian for coin or beaded scarves, to oriental shawl for fringe scarves. there are actual fringe skirts Ansuya often wears, you can find them under "accessories" "fringe skirts". Dahlal does not provide links so you ll have to search for yourself.

Moondancebellydance is cheaper and also offers fringe skirts, but dahlal is top quality. I can recomment them without hesitation. If you like the multicoloured scarves Ansuya s often wearing like the one in the free online class, you might want to contact dahlal and ask for unusual patterns for the "Single Row Coin Scarf", that is how the style Ansuya is wearing in the class is called with Dahlal. I recently ordered a VERY pretty black and red glitter pattern. They have unusual patterns not on the website pretty often, you just need to ask for advice via email.
Turquoise international is also offering very pretty coin scarves:
www.turquoiseintl.com/
this one s very pretty :):

So hope that gives you some ideas ;)
take care
