How to distinguish British, French and American interior design styles?

The difference between these styles is relatively small, so it is not particularly easy to distinguish ~ I distinguish it like this.

1, the British style is widely used in various shapes such as lines and columns, and influenced by the British royal family and religion, the decorative lines are exaggerated and orthodox, all of which are luxurious. English country style uses a lot of wooden materials to make furniture.

2. American style is a simple decorative style rooted in British style. It absorbs the British symbols and simplifies them, which is less cumbersome and luxurious than the British style, and is more direct and open in decoration and modeling.

I can't tell the difference between Italian and French. I think French is baroque rococo, and Italian has both French softness and Mediterranean frankness.

I don't know if this will help you ~
