Breastfeeding friendly outfit for my baby's christening

[Jellybean81]

I'd really appreciate help tracking down a lovely dress to wear to my baby's christening next month for under £100. It needs to be breastfeeding friendly for a large bust (G cup) - I was hoping wrap dress but I haven't been able to find any that are suitable. I'm a size 16 on top and 14 bottom although hoping to lose a bit more weight before the christening. Would be happy to consider alternatives to a dress and would ideally like something colourful. Any ideas?
