Take your fabric. The short side should be as long as your shoulders and arms and the long side as long as you want your kimono.
Fold the fabric. The good sides are facing each other.
Blue is the length of your arms and shoulders
Orange is the length of your armholes. Make them wide.
Green is the half of length of your waist.
Cut the pieces with the red cross off.
Sew. Remember, good sides are facing each other! Stitch the edges with the cross-stitch to tie it off.
Take the front of the kimono and cut it in half. Cut a v-neck. Stitch the edge.
Turn it inside out. Sew the hook and eye buttons on the place of the dots. And you're done.
