SHOES! help me! *not lighthearted at all*

[PreMadonna]

I need party shoes.

Problem is I am large (size 16-18) tall-ish 5'7 and very very unstylish.

I've looked at pretty sparkly party shoes and they all have heels. I can't walk in heels, let alone dance. I live in doc martens and crocs (sorry).

Also my feet are square so ballet pump shapes are difficult as I splay out all over the place and they look ugly.

My dress is black, lace overlay, knee length with sleeves. I rather like it but at this rate I'll be wearing bloody flipflops with it.

Please help me.

Well I have big feet and little money but I wouldn't wear any of these shoes! Sorry

Thanks for all suggestions. I'll look at some wedgy ones. I'm veering towards flats though. My friends all seem to be 5 ft tall and I feel like a big enormous giantess next to them already.
Party is on 20th

JD Williams, Shoe Tailor, Fashion World have nice shoes, up to EEE fitting too

I wear a size 10ww and always manage to get nice shoes so don't despair OP.

Hotter a Extra Wide (low) heels some of these aren't so bad OP.

Clark's do a wide fit in many of their styles too. But it's an ordinary wide fit rather than a really wide fit iyswim
