First, you must try a bow-tie.
A bow-tie is simple, yet it communicates the message of "hey, I am human too" , not to mention any cat with a bow-tie looks so adorable.

The second item every cat should always try on is a sweater.

Lastly you should implement a top-hat.
Nothing says "cover of cat fancy" quite like a gentleman cat with a monocle and a top hat. Not only is it cute, but it makes your cat look classy , sharp and flattering! The top hat is a definite must!
