October maternity wedding guest - plea for help

[BippityBoppityBullshit]

I feel like i've searched every corner of the sodding internet for a maternity occasion dress suitable for an October wedding and so I'm surrendering, consoling myself with a lidl knock off twix and asking for the love of god will someone please help me!!!!

The details-
Late October Wedding - in a church - so brr and I'm thinking i'll be wanting tights
I'll be 25 weeks pregnant - second child so sizeable bump
Size 8-10 but find size 10 maternity wear quite loose
I'm a pasty redhead
Not loving my arms right now so coverage would be good - although I realise I can add this.
Budget - I'm only going to be wearing the thing once so I don't want to go overboard and am open to secondhand/ebay finds

My fate is in your hands ladies - please help

I wore almost this exact dress - it was asos but a slightly different shade - to a wedding when I was 25 weeks pregnant. www.asos.com/pgeproduct.aspx?iid=6108129
It's very flattering indeed. Would add nice earrings and some class of a faux fur for October. I got lots of.compliments.

I wore a TopShop maternity dress to a wedding when pregnant. Just had a look and there are several on their website I'd happily wear, but depends on your personal style / preferences.

Isabella Oliver have a bitter chocolate coloured, long sleeved dress in their sale for £25 (was £109). It's the Evesham Maternity dress and its in size 8. Reviews for dress are good. Also available in cobalt blue in same size. They have quite a few other dresses too - the Neale wrap dress in dark ivy ( a lovely dark mossy green) - it's long sleeved and would look great for Autumn. It's more expensive at £89 but be used after pregnancy for nursing as its a wrap and tie dress.
