Ikki wears the whole uniform! But he keeps the left leg rolled up like this and the sleeves rolled up the same way. Also his hair is . . . probably in need of a serious cut but he'll just do that with a knife when he remembers/someone points it out. :|a
Shinichi wears the whole uniform in whatever proper way there is. :|a Occasionally he cover up his Mirror!eye with a piece of cloth. Occasionally he'll wear his red and white sneakers.
