I like the dress and the shoes OP picked. If OP has the figure then I say go for it.
Take a coat though, it's bloody freezing!
I second this!
That dress is stunning, love the shoes too.
If its the evening part you are going to then I think it will be lovely, if somebody came to my wedding reception wearing that the only thought I would have had is how lovely an outfit it is. If you are going to the day part then its a bit iffy dependant on how short it is on you. The model is 5"9 so on most women (I assume most) then they will gain a couple of inches in length.
