To the left is a chart of the striking points allowed in kendo shiai (matches) -- I included it here because it also shows a fencer in full armor, which of course includes the uniform.

To the right is the keikogi, or heavy cotton shirt. It is similar to the karate gi except it doesn't need to dislodge because it isn't ever grabbed, so there are ties to keep it in the proper place, and the bottom portion is sometimes quilted, like this one. The small blobs you can see near the bottom the the keikogi are embroidered kanji (japanese symbols) that identify the owner. The keikogi is put on first, then the hakama are slipped over the shirt.

This is the hakama, or pants. They are basically a pair of really wide pants that hide the movements of your legs. The hakama is tied on with the straps you see folded above it, front first, then back. I was taught that when you are in your dojo you should step into the hakama with your left foot first to show that you are at ease (as is the case with most cultures, because the beating of the left ventricle of the heart is nearer to the surface of the chest, the heart was thought to be left of center in the chest, so defending the left side is seen as paramount). When visiting other dojos, it is preferable to step in with the right foot first, a sign that you are keeping your vitals back from danger. The hakama have 13 pleats that are preserved by folding them carefully after use. They are quite comfortable and allow total freedom of movement (unless you tie them too low and then catch the hem with your foot and trip -- I speak from experience). Beginner student practice in only the keikogi and hakama so they can become accustomed to how the uniform feels when attacking. Later the bogu (armor)is added, which initially fells very cumbersome but eventually becomes almost nonexistant to the fencer.
