Wedding Outfit 2 - Ideas and Styling - Please Help Me!

If you regularly follow my blog, you will know I'm going to 4 weddings this year!  2 down so far, only 2 more to go!  One coming up is my sister's wedding, so I want to get the styling right, as the photos are likely to be sat on my Mum's shelf for years to come...

I've bought a dress from Phase 8 and it was very expensive.  I do like it, but I'm not 100% sure about it.  I might need to try it on again, or carry on looking to see if I find a dress I like better.

Anyway I've had an attempt at styling the dress - really only to get ideas for jewellery that would match, as well as shoes, accesories and makeup colours etc.  If anyone had any other suggestions as to what would work with this dress, please help me!!!  I find styling outfits, especially formal outfits soo difficult!  I'm relying on you ladies to work your magic...

Dress - Phase 8
Shoes - Nine West
Jewellery - Dorothy Perkins, Next, Warehouse
Scarf - Vintage (my Granny's)
Nail Polish - OPI
Eyeshadows - Accessorize and Mac
Eye pencils - Eyeko and Avon
Hair Feathers - Independent shop
Cat - blogger's own

Thanks ladies - all your help is much appreciated! xx
