well i think they [charity shops] are more likely to rag the clothes if they are as in this bag 1/ Cheap Brand Label , such as the Black Pencil Skirt with the Zip ..its Atmosphere ..[Primark] as they are unable to make any profit ..2/ Flimsy Clothing ,there are a lot of Polyester and Lycra Skirts that are just too fragile to resell..Wornout or looking the worse for wear ..and Tights well  obviously have to be ragged...its all about profit.
