I used to work at Hot Topic and I loved this set so much that I purchased 2 of them. I never wore the second set so it is brand new but the tag unfortunately has fallen off. I can't find the size on them but they are around a size extra small/small. I have included measurements in the pictures. The fabric does have stretch to it and the waste is elastic with a draw string closure. These are red and black and color. The pants have a red star pattern on them with kitty cats throughout. I should also mention that I used to have cats and although I tried very hard to make sure everything is hair free, sometimes there can still be hair on the product even after all these years.
