I ordered the Panda Bear with sunglasses light up shirt. It is really unique. They do run small, so order up a size or 2. The shirt is a really nice quality. It comes with a battery pack that has a pocket inside the shirt. You have to put batteries in it and then the panda bears glasses light up to music or noise! You will get alot of compliments when you wear this shirt! It is great for kids or teenagers or anybody that goes out at night. You cannot really see it light up in the daylight, but it is cute without the lights. This is a really, unique item and if you buy it as a present, you know whoever you give it to, probably does'nt have one already.
