England

England is one of the most popular Hetalia countries out of all of them. Thousands of fans across the world ship England and America as their favorite pairing, showing that England is an extremely popular cosplay. This could be because England is such a popular country in all of the English speaking world, and everyone, including former enemies, will get along with England.

What you need.
A proper English accent.
A love for drinking tea.

Start gathering supplies for your outfit early. Get your proper military vest, your blonde wig, your tie, and your collared shirt all ready and properly ironed. You can't be England without a properly ironed outfit; that wouldn't be proper.
