1. You can consider buying a slightly cute watch, a cute Doraemon cartoon bouquet, they like cute things.
2. My boyfriend is also a Leo, he has a strong self-esteem and cares about face! So the gift must be unique and innovative to attract their attention. For example, you can choose a box of handmade blessing chocolates, and then write your blessings on them. This is also a very popular chocolate I just learned recently. You can try it!
3. My husband is a Leo, I absolutely understand, the more expensive the better, the higher the grade the better, this can reflect the dignity of Leo and make them look face. They like luxury goods very much, and people who care about face do this! But it will cost a lot, dear, come on!
