I like it, too. I don't like this kind of sleeves, but I like everything else on the dress. The colour, the print, the length, etc. It's completely okay for the occasion. No need there for a colourful "look at me"-dress. There's also no need for jewellery. It would clash to much with the nice print on the hems. And the wrinkles someone complaint about ... well, those are just normal after sitting a while. Nothing to get all worked up over.
The hair is also okay. It would look a bit nicer if the fan would have blown it a bit more wavey and fuller, but that doesn't mean it looks bad. It's not perfect but completely okay.
