On the wedding day, the groom's suit should not fit too well to avoid inconvenience. Moreover, on the day of taking wedding photos, the groom should not wear fancy or dark underwear and avoid wearing white pants.
Brides should wear white wedding dresses when taking wedding photos, so they should prepare their own white or light strapless bras on the day of taking wedding photos. If you wear Chinese evening dress, you'd better wear padded underwear or steel underwear to beautify the chest lines.
If you take a friend with you on the day of the wedding photo, you can bring your own digital camera. If you choose clothes for wedding photos, you can take photos in advance, so that you can tell whether the clothes are suitable for the bride.
Some people like glasses, and if they want to take wedding photos with them, they should take off their lenses and keep only the frames to prevent them from reflecting light.
On the day of taking wedding photos, the bride should also bring the usual eye drops, because the bright light when not taking photos may sting her eyes and make them red.
