Opinions?

My formal is this year,
I guess it's like prom for Americans but here in Australia it's kinda different? Idk anyway!!!! 
I have fallen in love with this dress, I just want some opinions. Tbh I dot care but if I'm going to buy it I want people to love it just as much as i do. 
I have tried on a dress exactly like it- which is why I fell in love with it... But the online version is $450 cheaper
