A Krishna's Eye-designed oversized T-shirt sounds intriguing! For this design, you could focus on:

1. Visual Style: Consider incorporating intricate patterns and vibrant colors that reflect the traditional art of Krishna's eye, such as detailed mandalas or peacock feather motifs.

2. Placement: An eye-catching approach might be to feature the design prominently on the front or as a large, central graphic, possibly with a mystical or spiritual aura around it.

3. Material: For an oversized fit, ensure the fabric is comfortable and has a relaxed drape, like a soft cotton blend.
