Set of 5 multi-colored cotton blend undershirts. - Colors: Black, White, Blue, Olive - Quantity: Set of 4 - Material: Cotton blend Thank you for viewing. No brand label Only the black one is a bit shorter in length. I probably bought the set excluding the black one. Even though it's shorter, I think this is probably the standard length. Maybe it's because my child is small... There were also sets of 3, but the lengths were slightly different. I often had them wear the colored ones, so the white one is relatively clean, but there was a faint stain in one place. Thank you for your understanding regarding used children's items.
