Most costume changes in a film for a character

Madonna (USA) (b.16 August 1958) changed costume 85 times in Evita (USA 1996) as well as donning 39 hats, 45 pairs of shoes, 56 pairs of earirngs and 42 hair designs to transform her into Eva Per¢n (Argentina), First Lady of Argentina. 

The costumes were designed by Penny Rose and based on Eva's own clothes, many of which lie in an Argentinian bank vault. 

Madonna poured over thousands of material samples, choosing each pattern herself, before an army of costume makers went to work, taking 14 weeks to stitch, sew, bead and recreate Eva's wardrobe.
