It's a wedding one

[PotterBot]

Sis-in-law is getting married. She doesn't want lots of bridesmaids but wants all the children of the family to wear the same outfit. Has sent chosen dress around for us to buy its £60. I have to buy three, when the children already have suitable wedding wear.

Have suggested children wear their own clothes, this has not gone down well at all.

My feelings are that if you want someone to wear a specific outfit you should pay for the outfit not dictate how much the other person needs to spend to get into your wedding.

AIBU?

Unless you get together with the parents of the other kids having to buy this dress and secretly organise for your kids to belt out a few Sound of Music hits at the wedding. Your sis in law to be will LOVE it!! So long, fair well, auf weidersehn goodbye! Goood byeeee!!

I think you should all turn up in ripped jeans and fraying straw hats! Cheeky mare!

Get all the children in Halloween costumes, facepaints, the works

She wants it to look in the photos, like she had a huge wedding party with loads of bridesmaids, but she's not prepared to pay for that.
I would put the kids in outfits that work for them and you but clash with each other and the bridal colours!
