Love Victoria's Secret, I've only ever been to the one in Edmonton before this and well this is larger than that one, staff is welcoming and friendly from my experiences.
Only ever used the change rooms once and there always seems to be a line up for them and the time I did use them, there were still empty stalls while people were waiting to try stuff on....
I have noticed some of the bras do fit differently, for example the new show-stopper bra is a lot more stretchy around the band, but if you want to avoid the change rooms the staff is well in-formed and do know how things fit.
Victoria's Secret has a Semi-Annual sale, well, semi-annually lol, to clear out all the old styles and make room for new stuff, so if your like me and love sales this is one you can't miss! I believe it happens in early Winter & Summer.
Overall Victoria's Secret is great quality for the prices, and I love the variety of styles =)
