Buying [West] African textiles in NJ/NY/PA area or Online?

I'm looking to make a wedding dress for next year out of handcut voile lace & african metallic gold prints -or- brocade but I'm having trouble finding places to look at fabric. I live in northern NJ but I'm willing to travel to NYC, Philly, CT and anywhere in between to look at fabric stores that have a good selection in African fabrics. Stores with or without websites are appriciated, exclusive online store & wholsale outlets are ok too. THANK YOU!
