Great question Melissa :) You can't go wrong with any of the bridal stores in the Inner West. Parramatta Road in the Leichhardt/Petersham area have a couple of fantastic bridal shops. There is a place in Five Dock right near First Avenue, as you're approaching Great North Road that has a great bridal shop - across the road from the aquarium whether it is still there or not. The bus stop where the 438 stops before turning into Great North Road is right outside the place I have in mind, yet for the life of me I cannot remember the name.
I've never been in but there was a bridal shop in Crows Nest called Halo Bridal which had window displays that always caught my eye when I went past. Sadly the flagship store has closed down now, but it looks like you can still get in touch with them through their website, which has a huge range of gowns on it. http://www.halobridal.com.au/
Sweethearts Bridal Boutique in Blacktown has gorgeous wedding dresses. I haven't seen the men's clothing, or what they have for bridesmaids, but the bridal gowns are amazing... and they always have specials!
Thanks for your great answers! I agree with you Justine, although I have never been into the boutiques themselves the bridal shops in Liechardt always seem to catch my eye when driving through.
As a typical girly girl who loves everything wedding related, I must admit it is my dream to one day wear a Steven Khalil design, a relatively new designer who has absolutely boomed on the bridal scene. His incredible gowns have also been seen on many red carpets during the current award season. His boutique is situated in Paddington.
