What you need to fight in savate?
Technical skills? Savate technical regulations? Knowledge about allowed techniques? tactical skills?
You have to borrow from your uncle older integral dress (to proove that you do savate) and from you friend wrestling shoes or your running sport shoes.
I like also integral dress, but I like savate more, so I changed this fashionable clothes for two part dress (trousers and upper shirt) like French savate team.
And why countries like Serbia, Russia and Croatia force integral dresses? And why they always choose some weird lenghth of their dresses? Is this because they like to train in shorter dresses? And do they really need hardened savate shoes for fouette - kicks with the toe?
