These are all businesses run by women, with excellent customer service, who source their products ethically/in a socially responsible way. I know their products help support women and their families in Egypt, by providing work that they can do from home or in a respectable atelier.
Edited to add:
Coin scarves/belts are great for giving you the sound feedback that you are working your hips. They also have a bit of weight, so you are conscious that you are wearing something in the hip area which gives you a bit more sensory feedback of how you are working.
Farida has an excellent sale on for Zena coin/sequin belts for £10.
Zara has some lovely velvet based coin belts for £15.
