Wedding copy cat...

So me and my husband are coming up on our 1 year anniversary well when we got married his mother who is 40 was dating a guy. Now they are engaged and she is planning a wedding just like mine! Like same colors bridesmaid style and dress I'm flattered she likes what I did but seriously? Why copy what I did... and me and my husband aren't happy about this I hope she don't ask me to be in it or help...
