At a formal wedding, the bride and groom, bridesmaids and parents of the bride and groom all need to wear corsage, and the emcee, guests and witnesses are also eligible to wear corsage. Traditionally, the groom gives the bride a bunch of flowers, and then the bride chooses one from the bouquet and pins it on the groom's chest. The groom's corsage is usually the main flower in the bride's bouquet. As for the corsage of the guests, the principle is simple and compact. Remember, the bridal shop's corsage and scarf are embellishments, which should play the role of finishing touch and should not be the visual focus. A flower and some matching florets are enough. Don't let the corsage turn into a bunch of flowers, and the pedicel of the corsage should not be too long. The corsage was originally pinned to the left collar of the suit jacket. Some elegant suits have a buttonhole in that position, which is specially designed for putting the corsage. But now it's much more casual, and it's not rude not to wear a corsage on the right collar. If there is no ready-made buttonhole to put, put the corsage on the collar of the suit, and the pedicel is vertically downward, aiming at the position of the shoes.
