M. Ivan (played by Bill Murray) is a member of The Society of the Crossed Keys. This means that he belongs to an elite group of hotel concierges and attendants. It also means that when M. Gustave is in trouble, M. Ivan feels obliged to believe his side of things and help him out.

Like all members of The Society of the Crossed Keys, M. Ivan takes his job to heart. It is his passion and his raison d'etre. And this shows in the pride he takes when dressing himself. While this makes for an interesting costume it also, unfortunately, makes the costume a bit difficult to put together.

You can get white dress pants, a white dress shirt, black dress shoes, and a champagne colored bow tie easily. M. Ivan's overcoat, however, will likely need to be custom ordered from a costumer like the one linked here. His waistcoat is another unique piece because of its deep cut, so one like that pictured above is a close alternative.

M. Ivan's Society of the Crossed Keys pins are another key costume feature that will require a little DIY work using miniature keys. And, finally, his thick mustache in a truly vintage style is the last piece to this very unique costume that is as detail-oriented as the character himself.
