I have all 4 colors of the glitter belts and 7 belts altogether and LOVE them!!!! They function great and are fun and add color and sparkle to my workout outfits while teaching. My favorite color is the fuchsia one, which is beautiful!!!!!! The only reason that I did not give it 5 stars is because the last two belts that I ordered: the aqua and the red, do not have a black back. The aqua one that I received has a yellow back and the red one came with a light red/pinkish back. These can be seen when I am teaching my fitness class (because the inner belt is adjusted to my waist), and it bothers me a lot. My 5 other belts have a black back. Please make all your belts with a black back. Why mess with perfection? If you don't do black, it should at least be the same color as the belt-not that crazy yellow!!!! On a side note, I do not like the color of the red glitter. It does not pop. It is more of a brown red. I had ordered it to wear for the 4th of July, but it did not work well. I want to order more colors, but I only want belts with the black back, so please specify.
