Scoobs, what is Stepanek wearing!?! you have made me quite curious
let's see. the base material is fairly dark - sort of a brown or puce colour. there are sorta tan stripes vertical from under the arms to the bottom of the shirt, and a bit fat vertical tan stripe down the centre of the back.
Diagonally down from his top right to bottom left (ie from his right shoulder to left side diagonal) the material is a sort of mottled khaki effect while the rest of the top is the plain colour. this is replicated on the back (as well as the tan stripe i already mentioned)
the shorts show a similar design.
White socks and training shoes complete this outfit - a fiesta del failure.
