Question: how do you evolve eevee into espeon in pokemon sun?
Answer: Espeon. To get Espeon, you need to give Eevee a high happiness value. Which is easier said than done. Catch Eevee in a Friend or Luxury Ball for a good start, and then give it a Soothe Bell item, and level Eevee up, use vitamins, teach it moves, and feed it Hondew, Qualot, and Tamato berries.
