On April 15 (old calendar), the "Fukusei henkaku no rei" (Ordinance of dress code reform) was issued, which stipulated that naganoshi (stretched dried abalone used as a betrothal gift) and naga-hakama (long hakama trailing the ground) that had been used for ceremonial clothing since the beginning of the bakufu be discontinued, as a result, the official ceremonies became simpler with more practical ceremonial clothing.
4月15日_(旧暦)に出され、幕府初期以来礼服に用いられてきた長熨斗・長袴が廃止され、より実用的な服装による形式的な服装・儀礼の簡素化が行われた。
