For starters, it wasn't lost on anyone that Prince George wasn't as excited for the trip as his little sister seemed to be (he even looked sleepy upon landing in Berlin on Wednesday). Plus, George's outfit looked a bit different than usual on Monday because he wasn't wearing knee socks (gasp!).

Take a peek at their tour so far:

Now, people are buzzing about the red shoes bubbly Charlotte was wearing. As it turns out, they are hand-me-downs -- from her Uncle Harry! Prince Harry rocked the shoes back in 1986 at Highgrove House and in a portrait taken at Kensington Palace, and now the Princess of Cambridge is bringing them back.

See both Charlotte and Harry wearing the shoes:
