Something tatty is worn, shabby, and in poor condition due to age and use. It's beyond just being old; it's showing visible signs of wear and tear, like fraying edges and faded colors. Think of a teddy bear loved to pieces, with its fur matted and stuffing coming out. It's not necessarily worthless, but it's definitely seen better days. It implies neglect or insufficient care. Imagine an old book with ripped pages and a cracked spine.
