Looking for xmas party dress on ebay - brand recs please

[Trickymoments]

I can't afford to buy another dress
that only gets worn once a year so thought I'd have a go at ebay.
So far I've set up searches for Coast, Oasis & Warehouse.
What other brands/shops could I search for?
I'm 5'3, size 12 and like shift style dresses rather than floaty.
