The Karate Gi. Due to laws that prohibited fighting, people trained karate secretly, mainly at night. The white robe (gi) is said to resemble the sleeping robe and prevent authority from spotting the activity.
Hahaha, I had a month of BJJ classes (Couldn't do more, as my schedule became swamped) and the hardest thing, about the entire thing was correctly tying the belt to my Gi! Thank goodness for Rener's tutorial video! #EveTorres #BelieversBoard
