Kate looks radiant in the yellow dress. She is looking so relaxed these days. She really wanted that 3rd baby and with his birth she's a complete woman. 
I agree.
I think I have my answer to my standing question: one can find the answer by observing the tabloid headlines across the years, methinks. It's the tabloids who have 'trained' the public to cast a jaundiced eye on the labels the royal ladies are wearing. It becomes a very easy way to diss a royal lady by making the claim she's not supporting British industry.
I get it.
Certainly there are some media (like tabloids, which was what I was referring to) that peddle certain (spoiled) fish, but on the whole media (when not government or big business owned) do an excellent job of keeping the populace informed. Many journalists go to jail and some risk their lives to get the truth out. Distrusting all media is just as distorted as trusting all media. Discernment is key, I would say.
Fun!Wouldn't it be cool if one day Kate and her sister-in-law show up in their yellow dresses together?
Not sure about the make-up but that may be a photographic effect. Hat is interesting. It's a put-together look emblematic of her style all 'round (imo). Great earrings! 
'Vintage'? Looks pretty normal to me.
