At its meeting in December 2011 the BWF Council agreed a number of changes to the General Competition Regulations.
This included changes to wording of GCR 23 - Advertising on Player's Cothing which now reads as follows :
"Adveritsements may appear on the following locations : left sleeve, right sleeve, left shoulder, right shoulder, left collar, right collar, right chest, left chest and centre chest. Each advert must be 20 square centimetres or less. Other than front of shirt, only one per location; and there must be no more than five in total. National flags or emblems for the purpose of this regulation count as an advert." see bwf link
This revised wording came into force on 1st January 2012.
Further wording alterations to the clothing regulations were agreed but do not come into force until January 2013.
