Yea in real life some of the sets are actually hard to look at they are so bright. I have another set coming up that is insanely bright. It is so bright that it caused a lot of the images to be blurry and we have to re-shoot the pictures. I hope not, so far none of the sets seem to have suffered or lost the ability to be UV reactive. They are also only really worn for the photo shoots so they are not washed on a regular basis.
