Levi's women's T-shirts

Levi's measures in inches: W for the waist, L for the leg length. The model number (501, 511, 505) defines the cut more reliably than the size. On a pre-owned T-shirt, the neckline is the point of no return: once stretched, it does not recover its shape. Then check the prints, which crack where embroidery holds, and on fine knits look for pulled threads against the light - they do not show from the front.
