Three grades, no surprises
Grade A, like new: worn once or twice, or never. No marks, pulls or odours.
Grade B, gently used: light signs of normal wear such as soft pilling or slight fading. Every mark is photographed up close.
Grade C, visible wear: honest flaws you can see, such as bleach marks, small holes or a loose seam. Priced lowest, and shown next to a ruler.
