So basically you press the outfit sprites which are on the clothing rack. Please don't move them (nothing stopping you but it will get a little messed up looking). Also my guy Link has been out in Tabantha and needs some clothing, fast.
All credit due to the creators of Zelda who are amazing. Also @yaymeiwin who taught me how to get Link to change outfits via a google search result https://scratch.mit.edu/discuss/topic/41595/?page=1#post-343750. So yeah.
