Mobile dress agency...?

I own a mobile dress agency, collecting good quality, excellent condition clothes from individuals and selling on their behalf. I do this via 'pop-up' events in various venues (village halls, etc) across my region. Clothes are hung on large rails, shoes on tables, accessories on various dummies. I like 'shabby chic' type style and am wondering if anyone might have any ideas how I might be able to temporarily 'decorate' my surroundings easily,to 'pretty it up'. Many thanks
