Avery Chin and Sylvia Lim, a pair and partner performer, are costume change specialists like no other. They could top the Guinness Book of World Records with flair, breaking the world record with little over four seconds to spare and without any effort.

Sylvia slides into outfit after costume, as if by magic, with just a split second between each change. A total of 18 modifications were made during the course of 19 outfits. This breaks the previous best by two outfits and a long time.

Guinness World Records usually exist as a challenge to anybody who attempts to break them. Avery Chin and Sylvia Lim, though, make this one seem simple. Watch as Sylvia breaks the previous costume change record for one person with a performance that appears to last an eternity.
