When are you too old for leopard print?

I don't think it has anything to do with age, you either like animal print looks or you don't.It does seem fashionable at the moment, all things animal-y, if you like it then wear it ( tell your DH not to be an old fogey)

I always think of leopard print as the preserve of older women.

Perhaps your DH just doesn't like it! It sounds quite tasteful to me.

I'd wear it
I wouldn't wear a leopard print coat but I'd wear shoes a la Mrs May

Never if you like leopard print then go for it!
