Haul videos have become a recent fashion phenomenon whereby people post videos online showing off their purchases to a global audience.
A limited number of people will be chosen from the selection day to return to mima on May 19 to wear the jewellery, which is never normally worn, and to film a haul video blog that will broadcast online around the world.
"Haul videos" are online videos created by young women showing off their fashionable finds, many of which have quickly gone viral.
A quick search on YouTube yields nearly half a million haul videos, with several getting millions of views.
They continue to make haul videos as well as offer beauty and fashion advice on their Web site, ElleandBlair.com, in which they tell readers to "think of us as your super savvy big sisters."
There are more than 110,000 haul videos on YouTube, with 60 having received more than 100,000 views.
After the shopping spree, the girls recorded haul videos which were posted on the company website plus Facebook and YouTube.
