Family bless them

[WantToBeAMamma]

Aibu to think it's OK to let my 7 daughters wear bridesmaid dresses that they wore for there uncles wedding 8 weeks ago to there 1st cousins wedding or would I have to ask my Sil if its OK.

Why the "bless them" in the title? And yes - echoing everyone else, it doesn't matter what relation's wedding it is, unless they've been asked to be bridesmaids you don't dress 7 daughters in bridesmaids dresses.
