Traditional Cambodian weddings are colourful and extravagant. The bride and groom wear matching colourful outfits and they can change outfits several times during the whole day of ceremony and reception. These outfits are, more often than not, rented from a wedding shop like the one in this picture.
To those adventurous, there are photo studios in Phnom Penh that offer costumed portraits. If you love dressing up, like some tourists I know, have your photos taken garbed in Cambodian traditional costumes as souvenir. Many of my expat friends have already done it but I haven’t yet. I’m considering it though.
