 As such, I agree with you that since the groomsmen are wearing blazers and khakis, the event is semi-formal.  Having said that, I think there is more leeway in women’s fashion such that a bride may elect to wear what she feels appropriate.  At least it seems so here in California (and at weddings at the beach).  So while some may think her choice is tacky or a wedding faux pas, it is supposedly “her day” and within her "right" to wear something more "traditional".

The reality is, though, that the bride tells the groom and the groomsmen what to wear 99% of the time. And if she's going to wear a full length dress with a poofy skirt, she should tell them to dress up more. The simple dress you posted that is full length is a little formal, but not too bad for a semi-formal wedding. I'd pass it, although it would be perfect if it were ankle length instead of floor length. 
The bride can absolutely wear whatever she wants.  If it gets posted to the intertubes, though, mean old ladies who are total strangers are going to snark on it.  (I'd never snark at a real wedding, but wedding pictures on the internet are fair game.)
