Cat has dance gear that's soft rather than tight to start with (7)
I believe the answer is:
leopard
'cat' is the definition.
(I know that leopard is a type of cat)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for leopard that I've seen before include "Spotted big cat" , "Powerful cat" , "Spotted animal" , "Spotted feline" , "Large spotted cat" .)
