Help me find a dress for a black tie event

[NutterlyUts]

which is in october.
I know its a long time away, but I am Far Too Fat and so I want to find a dress I like to give myself a goal. I don't plan to buy the dress until September but I want to put pics of the dress everywhere to give me motivation to slim down a bit.

I am 5'7 and currently a size 20 roughly. I am not a girly girl but I do plan to get my nails/makeup etc done so as to be completely gorgeous and unlike me. I have a spare tire I wish to hide as much as possible, and I am a shape best described as a wheeble - I have acres of hips/butt/thighs and not much in the boob department.
I have dark brown hair, grey eyes, am pale and I have absolutely no idea what colour/s suit me.

I don't have a budget in mind, but I don't want to spend stupid money.

with tha last dress there i think id have astatement bracelet instead of a necklace

like www.monsoon.co.uk/invt/18456803 this]]

or maybe a necklace like this?

this bag would go with the last necklace

or do you think thats too much?

id have cream or ivory shoes then

wow

simple

classic

Lovely black and cream dress, love the "wow" bag but black shoes only. Cream ones always look like you're a bridesmaid.

yes i agree

black patent slingbacks or wahtever

have a massive trying on session in Monsoon to see what shapes / styles really suit you. Then you can target your search.
