Yay: proper senior royal-type duties, nice hair on Kate and a nice photo
Boo: ANOTHER blue dress?
There were a bunch of people predicting what Kate would wear and the options where
1-blue and yellow dress
3- dress with sunflower print.
The Ukrainian flag is blue and yellow(the blue a very similar shade to what Kate is wearing), their national flower is the sunflower. Kate always does theme dressing, and by wearing blue, which is in the flags of both countries, she's pointing to what they have in common. Honestly, I'm slightly disappointed she didn't borrow the Queen's sunflower brooch for this even though I know it's not nearly important enough for jewelry loans.
