mission impossible - pre teen purple dresses

[shouldwestayorshouldwego]

We need dresses for a funeral, ideally purple as they don't want to wear black and dh says should be mourning colours (he wasn't happy with navy!). 135cm and 155cm. They want to wear same dress. Skater style suit them best (and then might wear again). Dh says not school uniform. Ideally long sleeve (their preference), must have a sleeve. Must be here (uk) within two weeks. Found ideal one on Amazon but seller let us down. Need to be from reliable source. Not too expensive as they say they might not want to wear them again due to feeling sad. Help!!

There is just very little purple about at the moment and not many sleeves either. It sounds like the 3 of them are making this even harder than it needs to be, TBH. This might be too informal but maybe not.

To be fair the sleeves is a sensory thing, so it is either sleeves or we have to get cardigans too. The colour is picky as there are some navy dresses which I am sure would be fine.
