Wedding outfit needed

[Pennies]

Though not for me, but for my DD's - who will be 23months and 7 months by the date of the wedding (end July).

I want them to be dressed similarly but not excatly the same (e.g. dress of same style but different colour). Wedding quite posh but not overly so.

Can anyone help?

DD was 8 months when my DB got married and i got her a gorgeous white dress from Monsoon with a little pink shrug cardigan, also little white matching shoes.
Monsoon is a good idea I would say
