Dd - bridesmaid next weekend with Dn for a mutual relative - bride picked dresses - we paid. Not my taste but fine. I told sil we had got some ballet pumps for dd to go with it asked if she wanted some for dn - said no would do own thing. Now sil has convinced mil that both will wear same shoes with a 1.5 inch heel and ankle strap. Dd hasn't worn heels before - I think it is unnecessary and she is only 7 so not awesome for dancing and playing post wedding - basically will be useless. Dn little older and used to heels.
I just said wear different shoes - they will still have the same dress and look fine - apparently I am massively overly precious. Really not sure if Iabu or not!
