I got a fantastic dress from Primark last month and… it immediately ripped. I’m super sad about it. But while trawling ebay for a replacement (I have not found one yet) I did find a couple of dresses that would be really good for low cost Doctor Who cosplay:

Clara’s Journey to the Centre of the TARDIS dress option:

On ebay for £5

River’s The Husbands of River Song dress option:

On ebay for (currently) £2.07

They’re far from perfect obviously, but they’re not bad!
