Please help me find a dress for my DD's christening

[Peanut15]

Hi,
Despite trying I'm not fitting into any of my lovely dresses. DD's christening is in 2 weeks and I need something to wear. Got rather upset in JL today as couldn't find anything suitable.

She's EBF and only 3 months so it ideally needs to be a dress/outfit I can feed in.

I'm 5ft5 size 14-16 bottom, 12-14 top. Basically, I'm still really curvy after the birth and the weight is all on my thighs. This looked ok ish today but I wasn't sure it'd be smart enough.

Should have said budget is up to £250 but that would have to include shoes if I needed them
