Hi there! I live in Sydney and think the Maison (the large store on George St) is incredible! It's my absolute favourite and my SA - Olivia - she's wonderful! Another TPF'er recommended her and I am so glad they did! I can't speak highly enough of her..
I'm sorry I don't know the Brisbane stores particularly well so can't help there.
You will always get a dustbag when you purchase and mostly always receive a box. I don't think I've ever NOT received a box... that said, I have so many boxes that I'm beginning to think I should create an LV box Xmas tree this year...
My tip is to go during an off-peak time, so you don't feel rushed or overwhelmed. Don't be shy about asking to try stuff on and walking over to the mirror to see what it looks like on.
Otherwise enjoy!
Thanks for the info! What time do you think is off-peak for an lv store ahaha?
