Copycat bride

Do whatever you were going to do in the first place. Does it matter if your colour schemes are similar or it’s a similar venue? It’s all about you and your partner. Keep focusing on that!

I agree - use the date that works the best for you and your partner! It's your wedding and it will still be unique to you on the day ? I'm sure that the guests won't see the similarities you're concerned about. This happened with a few girls in my friendship group (one girl in particular thought that a friend was copying her style). Ultimately, they were both still very different weddings and lovely in their own way, and the two women are still friends. If you're really concerned, you could try not to discuss too many details of your wedding plans with your friend, if that's possible without jeopardising the friendship?

Definitely do the right date for you and don’t rush! I’m getting married after three friends and have no doubt there might be some similarities as we will all subconsciously be influenced by what’s on trend as well.

people rarely remember the decor details (unless it was really spectacular / unusual!) they remember having a good time with friends and a party so try to remember that too and not stress too much?

You could always do a Rooney and say you'e changing the date to just your friend and see what she does. If she changes it you really do have a copycat.
