The font used for Jimmy Choo logo is University Roman, which is a display serif font designed by Mike Daines & Philip Kelly and published by Adobe. Here's the download link.

University Roman is based on Speedball hand-lettering. Designed at the Letraset Type Studio in 1983, University Roman is notable for its narrow capitals with crossbars that sit well above the median line.

This unique roman design evokes a romantic air in display work such as packaging and advertising.
