Where can I buy a cheap party dress online or in shops in the uk?

It's my school prom coming up soon, its not a big prom, so Im only looking for a cheap party dress that is nice, does anyone have any ideas where I can find a site online or a shop ? My budget is around £20, possibly upwards but Im not willing to spend over £30 Ive already checked places like new look, quiz, topshop and next, but I either dont like their dresses or they are too exspensive, does anyone know a good place?

Primark or BOOHOO. I would do BOOHOO. it's a online shop with cheap dresses. There's also asos sales.
have you tried republic? some of the dresses are more expensive than that but you should get something for around that price (depending which brand you go for ) go on www.republic.co.uk and click on dresses then there is a price filter down the side
Check out the charity shops. People wear dresses once and give them away.
