Couple navy blue small carnations would do it....

Instead of carnations, see if they have some dark blue alstromeria, or trumpet flowers. They're small, but, they'll resemble in style the large vanilla colored flowers in Sonya's dress.

I will look for whatever they have in dark blue... there weren't a lot of choices in dark blue! - Lots of yellow.

They did have those bouquet form things!
