I think Rachel T.s review is spot on. I made an appointment for 7pm - I too was a little taken aback by the random house on the side of the road, in fact I drove by it the first time and had to make a U-turn to go back. Prior to this place my two previous wedding dress shopping experiences had been at White Toronto and Beckers, so a completely different atmosphere. That being said this place was fun and totally relaxed.
It was just myself and my gf - we had the place to ourselves. I had a few ideas in mind and told them what I was looking for. There are dresses all over the place, and as Rachel mentioned it's really hard to look through the dresses, we were very reliant on the consultant to pick ones out for me to try on. She keep disappearing and re-appearing with different dresses. I am quite blunt about what I do and don't like which helped, but you do need to be decisive. She was also quite honest and had a no nonsense attitude which I very much appreciated. I didn't feel as though I was being pushed into buying which also helped.
In the end we came away with the style/cut that looks best on me - which was the goal of the day. Not sure if it is going to be THE dress, but it was a great starting point and a really fun way to spend the evening.
Oh and the mirror upstairs - best skinny mirror ever!
