i don't know about dahlal's assuit, but i have purchased from this guy before
http://stores.ebay.com/e-kenoz
he shipped very promptly and the assuit was very nice. not like the antique-totally-covered-in-metal type, but nice for modern assuit. the good thing is that you see the actual piece in the auction listing so you know if you like that pattern.
hope you find what you are looking for. maybe post pics if you make a costume out of it?
