I shopped at Golden D'or many times and it had a great selection of high-end fashion fabric. Another favorite for fashion fabric was Wherehouse Fabric Outlet on Perth Street, just off Harry Hines. I never shopped there for quilting fabric. But from my previous trips, I can make the following recommendations.
Do go early, and intend to spend a lot of time. And don't dress up. Some of the stores are dusty, and a few have large fans rather than air conditioning. Jeans, shorts, capris, etc. are the order of the day.
Most of the fabric stores on Harry Hines and Perth streets close at 5 pm or even 4:30. On Saturday, some used to close at noon. Most are closed on Sunday.
Do not stay in the neighborhood after dark. I can recommend Mama's Daughters' Diner No.2, at the corner of Harry Hines and Royal Lane for lunch. It is locally popular and serves home-made pies.
Warmest Regards,
Donna
