Mad4Mod has a small display window with a few mannequins in it, but don't let the size of that window fool you.
Upon entering the store, you find an overwhelming selection of crazy and fun items. The prices are more than what you'd pay next door at Rag, but you're not just getting recycled clothing (well, technically you are)
The gentleman running the store when I stopped by was really friendly & pretty knowledgeable about the curiosities and the collectibles in his store. He even brought out a book to help us place a clock/radio ball, and to give us more info on the colors they came in back in the day.
Budget yourself some time to look through the selection of Chanel, Dior& other purses, the quilted turtle skirt, large selection of morning coats, vintage wedding dresses, tables (in very good condition) and other items. You can find things for 5$ here, and you can find them for $150.
