Prom dresses in Swindon/Cirencester/Marlborough sort of area

[YDdraigGoch]

Need to start looking for a prom dress for DD15. Swindon is our nearest big town, but Cirencester, Marlborough, Bath, Bristol, Reading all within shopping distance.
Where should we go?

Have a look at TK Maxx, Debenhams, Coast, John Lewis, House of Fraser.

Thanks Dexter. Tried HoF, and Debenhams - couldn't find anything that was suitable for someone under 50. TK Maxx - really?? Never been in there - was under the illusion it's full of cheap crap. Am I wrong?

TK Maxx is great! They had loads of nice prom dresses when we looked.

Cool. Will check it out at the w/e. thx for the tip.
