The reason why I am looking for lion stuff online since last week is because my cousins will be playing at the concert recital of Yamaha in 19 East on July 1 and this is the look that I'd want to achieve:

Of course, I don't own such a pair of boots so I might end up wearing a pair of sneakers but still, I want to achieve the look.
