The shape of the omoteginu is no different to that of the hitoe or uchigi; however, since it is the outermost kimono that covers the other kimonos of the juni-hitoe, it is usually made of luxurious materials such as futabe-orimono (silk double weave).
形は単や袿と変わらないが、一番外側に羽織る着物で目に留まるため、他の着物と違い、二陪織物（ふたべおりもの）などの豪華な生地から調製するのが特徴である。
