Not all the ideas in this book are very easy to rework into clothing... because some of it is about gilding fabrics and accessories or using heat melting friendly plastics... so I’m not sure all the techniques would survive the washing machine...
But in belly dancing the more extravagant the costume the less likely it is to be washed, there are other freshening techniques like airing, steaming, spritzing with vodka mist... but some of the effects would be glorious on very impractical clothes.
