Singer-actress Jennifer Lopez reportedly has a high-tech system to remember everything she wears so she does not repeat her outfits. Lopez, 46, uses a database to help her pick her outfits. “She had her feet up at a meeting, and someone noticed that she had a bar code on her shoe and asked her if she borrowed them. Jennifer laughed and said no, that she has her own internal bar code system on all of her closets to digitally keep track of what she wore and when she wore it, so that she isn’t caught wearing the same thing twice,” a source said. The database also has a picture of the clothes or shoes with details about the size, colour and the date when she was last seen wearing. It can also tell which outfits are kept in her New York home and which in her Los Angeles residence.
