Hi,
So I'm a bridesmaid for my sister in laws wedding which is at the end of April and I will be 39 weeks pregnant! 
She has said I can bow out at any time if it become too difficult, and is trying to be accommodating. But I don't want to let her down, and think it would be lovely for her future niece to be involved (even as a bump)
She's decided on a colour and shop to buy the dress from, only thing is they don't do maternity dresses! I'm currently wearing at size 14 at 24 weeks pregnant and have a fair bit of room in it. I tried an 18 and it swamped me and I just can't imagine it looking flattering.
It's high waist/empire line style. So just debating if I really need to go up an extra two sizes?!?
Any advice?? Do you think an additional two sizes would really be necessary? Or maybe just another one as it's mainly belly growth?
