A Sarashi that is too small to cover the torso or is especially revealing, leaving the character's Breasts or Midriff exposed.
To qualify for this tag, the sarashi wrappings should be reasonably secured tightly on the torso; in other words, it shouldn't be too loosened or mostly unwrapped, otherwise it is an Undone Sarashi instead.
For female characters, a budget sarashi is usually a Chest Sarashi that minimally covers the Breasts, often resulting in hefty exposure of Cleavage and Underboob.
