綿帽子

Compound of 綿 (wata, “cotton”) +‎ 帽子 (bōshi, “hood, cowl”).

綿帽子 (hiragana わたぼうし, rōmaji watabōshi)

1. An all-white hood or cowl, worn as an alternative to the tsunokakushi, and the Japanese equivalent to the Western marriage ceremony's bridal veil; its purpose is to hide the bride's face from all others, except for the bridegroom, until the end of the wedding ceremony. It was adapted from the katsuki, a hood worn outdoors to keep away dust and prevent from the cold, by married women in samurai families, from the Muromachi to Momoyama periods, before being taken up by younger women from the Edo period onwards. Like the shiromuku, its worn in concert with, the wataboshi is a symbol of innocence and purity; its worn only outside in outdoor receptions with the shiromuku-only, not with coloured wedding iro-uchikake kimono, or during indoor receptions.
