Animation/Art Question for Unity

We are working on a side scroller game and have the base game nearly complete. To start adding more content to the game we are going to add hats/outfits/items for the character to unlock and equip.
My question, is there a way unity can just place it once purchased on the existing animation art, in hand or on head or do all the frames need to be redrawn to include said hat or Item?
I am not too familiar with unity, I do all the art for our game but before I went and made multitudes of various versions of each character holding/wearing different combinations of items It seems like there should be an easier way.

Thank you for your advice.

Presuming this is a 2D game, you could have the hat (or whatever) as an individual sprite and simply attach it to some point on your existing character. If you parent it to your player’s head, it should stay with the player’s head and move as it moves. I’m working on a platformer right now where the player can choose from 7 characters and 5 different outfits, which are just another texture added onto the character. Easy peasy :wink:
