19 weeks pregnant - what to wear to a wedding?

[sotough]

I'm going to a wedding next weekend and have no idea what to wear! it's at a hotel and not massively formal i don't think but will be reasonably fancy (it's a beautiful boutique hotel). Help! I am 5ft 4in and quite petite build. bump is neatish. wedding is at 4pm. no particular budget - prepared to spend for something special. any ideas anyone? Isabella Oliver stuff is all dark colours...

I went to two weddings at this point, I wore wrap tops and trousers with fancy but comfortable shoes I think. But then I'm not petite and bumps were never neatish! I just accessorised quite a bit. Wore pale pink wrap top from JoJoMaman one time, they do a variety of colours and v.v.comfortable and glamourous.
Or try Crave?
