For a dressing up thing, so quality and condition isn't important, but cost is. I've tried gumtree, eBay, local selling groups on fb, oxfam wedding dress site, but either nothing or the items are too nice and expensive. Also tried fancy dress places but can't find anything similar.
I'm thinking full length puffy ball gown pref white or very light fabric. Can look really really tacky and that's ok. There must be somewhere I've missed? Or will this be a charity shop challenge that will likely never be found...
