I, personally, am a card-carrying member of Team Messy.
As of today, you can buy Sussex Squad or Cambridge Crew hats from my store. They’re comfy and cute, they come in black and navy, and I’m excited to see if one is more popular than the other. (eyes emoji)
If you want to show your dedication to one royal house over another, you can order a hat here. I’ll be back with more royal thoughts in a day or two, but in the meantime stay safe and wear a mask!
