It’s not technically a ballgown. But I feel like this is the closest we’ve seen of Sienna Miller in a ballgown? 

I like parts of this dress a lot. I like the studding along the stripes. I like the size of the stripes. I like that the stripes look like pleats but also like individual strips of fabric. I like the black with the champagne metal combination. But I do not like the swimsuit strap style. As previously mentioned, this is not my favourite cut on a dress. I wish another option could have been considered. 

Also I’m having split feelings on the hair. I get the look she’s going for. Why isn’t it totally working for me? Is it because the headband straps are exposed at the back? Tell me what I’m rubbing up against where this entire look is concerned?
