I think there are still a few lengths on ebay, my main page on my dress has a link to the seller (exoticfabrics-us) and this is the microsequin in pearl white. It’s much less pink looking than my last lot so I think that has more to do with the direction of the sequins than anything else.
5yards is just enough to do a full dress taking in to account careful toping and tailing. Also I used a very historic skirt pattern which uses minimum fabric for maximum effect.
