Go out shopping find the most adorable clothing you can find. Look for colour and cuteness, but, if you don’t love and don’t think it would look good on you, put it back. Don’t buy something you don’t like just because it is Kawaii.
Try finding old or used clothes and add lace, bows or other cute attributes. Many things that don’t seem kawaii can look great with some changes. For example, you could add cute animal stickers to white sneakers. Try adding lace to a normal skirt.
