Incredible Dress-Up 3-Piece Set I bought this for my child, but it hasn't been used much. Since there's no specific size, it's a great item that can be worn by small children to women's sizes! The "i" mark can be detached as shown in photo 4 and attached by clipping it onto your clothes. It should clip onto most clothes, unless they are very thick, such as sweatshirts. The upper circular part lights up when you press the lower part of the "i". It has been stored at home, so the batteries will be included when shipped, but please replace them yourself if the light is dim. If you put it on a red outfit, you can instantly become ready for a Halloween cosplay! The eye mask has creases. Also, please note that there were initial imperfections like misalignment and lifting, so please be aware of the imperfect construction. This is a private seller, so please understand that it is a used item before purchasing. I am selling another one of the same item, so it's also recommended for siblings to wear matching outfits!
