Inspired from the Let's Go series, naturally. Now, I couldn't find any eevees on my trip to Japan, but I did see a lot of signs advertising the game in question. I like this particular outfit for eevee, it just seems to add a dimension of cuteness that had me really wanting to buy the game. Now that I played Sword/Shield I don't think I'll get it now XD
