[Futokoro* — A Deep Pocket Full of Unique Expressions], super interesting article by Tofugu about how futokoro came to be used in many Japanese expressions.
*Futokoro is the “pocket” created between the kimono left fold and a woman obi. In the past, women used it to put away their hakoseko (kind of wallet holding tissues, changes, some lipstick, etc)... or even a kaiken dagger! Nowadays, it’s still often used to carry items (though cellphones took the place of daggers :P).
Tamoto is the other simple “pocket” used when wearing kimono: it simply refers to puting things away in your sleeves (and then often forgetting you put them there xD). Accessories like tabako-ire also existed, check this note to learn more about them.
