The trend of weddings in Vientiane is to have these fancy flower decorations that can amount hundred thousands dollars. Not too far from home, I have admired (on the internet) the most jaw-dropping decoration from India or Thailand. Among the florists, I am admirative of the creativity of Rainforest. They seem to serve all the aristocracy and business tycoons of the country. Have a look at their website for a few Bollywood moments.
