I have purchased the dress at a salon - it was a new sample dress, off the rack. I got it on the 2nd day they had it out on the rack, so it had no wear or dirt on iot. It did NOT have an Allure Bridal tag on it - but it's the exact Allure Bridal dress style 9365. If it's not an authentic Allure Bridal dress, it's an incredible copy with the exact same lace and style. I doubt anyone can copy a dress THAT well, but I could not confirm the authenticity with the bridal salon. So if you're brand-conscientious, I cannot guarantee the label.
I have the dressmaker modify the dress to shorten it to fit my 5'4 height without heels (I wore 1 inch flats), AND to add the straps. The straps are strong and will hide a normal size bra underneath it. You can easily take the straps off. The dress has not been altered otherwise (in the bust or the waist areas). It can fit street sizes 8-12.
The dress has a very strong metal corset and will push (and hold!) your boobs up in a very nice way up, so that's a consideration.
The dress is in a perfect condition, I used it for an indoor ceremony and reception and for some pictures outside - I walked on a pavement on a dry day. The dress hasn't been dry cleaned - but it's not needed. It does NOT have any smells. If you feel like it, you can spot-clean it but it's not needed.
