Clothes During The Academy Awards

Academy membership is divided into different branches, with each representing a different discipline in film production. Actors constitute the largest voting bloc, numbering 1,311 members (22 percent) of the Academy's composition. Votes have been certified by the auditing firm PricewaterhouseCoopers (and its predecessor Price Waterhouse) for the past 73 annual awards ceremonies.
All AMPAS members must be invited to join by the Board of Governors, on behalf of Academy Branch Executive Committees. Membership eligibility may be achieved by a competitive nomination or a member may submit a name based on other significant contribution to the field of motion pictures.
New membership proposals are considered annually. The Academy does not publicly disclose its membership, although as recently as 2007 press releases have announced the names of those who have been invited to join. The 2007 release also stated that it has just under 6,000 voting members. While the membership had been growing, stricter policies have kept its size steady since then.
In May 2011, the Academy sent a letter advising its 6,000 or so voting members that an online system for Oscar voting will be implemented in 2013.
