I first saw the photos not long after I'd woken up this morning, and it was such a lovely surprise to wake up to. Little Charlotte is a beautiful baby, and she also seems to be rather happy too, which is cute to see. I think she looks the most like George, although in the photo of her with the baby walker, she reminds me more of Catherine.
I personally loved all her outfits in the photos, and I thought it was sweet how they had colour coordinated her bows with them. I think British royal children just seem to wear traditional clothing for official photos and events, but unofficially I can imagine that they wear more modern looking clothing, but of course I don't know that for sure but the outfits Lady Louise, as an example, wears for less formal dressed events like the Royal Windsor Horse Show, are more modern in appearance than the outfits she wears to more formal events like Trooping the Colour.
I think the dresses she wore here are more timeless or vintage than old fashioned, but that's just how I personally perceive them and we all have different opinions on what's old fashioned and what's not. I also think traditional clothing suits girls better than boys in most cases.
