I'm off to my cousin's wedding in August. I'm not great with wedding clothes; my only wedding experience as an adult has been a bridesmaid at a wedding last year so the bride chose the dress, and before that I was young enough for my mum to dress me 
I don't have a massive budget as I'm a full-time student and I have a 10 week old baby (which should give you an idea of the mummy tummy I've got, I'm working on it but it probably won't be gone by the wedding due to ab muscle problems), even the Debenhams one is making my bank account sob a little. I'm stuck between these -
Dress 1
Dress 2
Dress 3
If the answer is 'none of them', any similar ideas (on a tight budget
) that I could wear? I'm somewhere in between hourglass and pear so fair-sized bust and wide hips, fairly narrow waist. Don't want anything too clingy due to mummy tummy. Any colour is fine other than white (obviously) and baby pink (bridesmaids).
Thanks in advance
