Children's clothing for a memorial service

[Toofewshoes]

We are attending a large memorial service for a family member and my DH and MIL want the children in full school uniform. I would rather they were not of their full uniform, they will wear the trousers/skirt and shirt/blouse with their jumpers but I think their blazers unneccessary. They are 10, 8 and 4. What would you do?

Wear and discard? Surely they will be there for longer than 5 minutes?

I would just send them in uniform for the sake of peace tbh. We sent our girls to a recent funeral in black pinafore dresses and cardigans from Tesco uniform shop (although they don't wear them at school)
