I think those earrings are beautiful and would work very well with an upstyle hairdo. The carnations though ..I don't know, to me carnations are the petrol station coffee of the flower world (convenient, budget-wise, sometimes can look/taste pretty good and does the trick as a placeholder caffeine, but you wouldn't find it at a wedding and the smell gets to you after a while), probably because in NZ they're mostly only bought from petrol stations, so I have an inherent cultural bias against them as a wedding flower!

I'm not sure how else to put it - basically, nothing against carnations in of themselves but I'd be surprised to see them at a wedding. Maybe that's not a bad thing though, being original? I guess it's different in the US.
I can see they give a really nice bunched effect and would be easy to dye-colour (although again you'd be dependent on the florist getting the shade right) - is it that bunching effect you like? I say this because I seem to recall hydrangea bouquets posted by someone earlier in the thread - they also give a neat bunching effect, and should be easily available in soft purple/lavendar shades (we used to have them in that shade growing in the back yard when I was a kid).
For example, this one, although not the right colour, is a similar idea to the last bouquet you posted (tight rounded shape with the roses) but uses hydrangeas instead of carnations:
The other thing is if you want small decoration pins they may not show up well against carnations - I almost didn't see the pearl pins in the close-up white bouquet photo. A larger pin like a diamante initial pin should show up well though, especially against colour.
